Once in a Lifetime

I just finished it a week before and I really loved it. I love the story, I love the intrigue, I love the characters! It's different from the rest of the AVNs, it deserves the highest of praises.

Wow! just finished playing this, it's so good!! I loved the epilogue slideshow with all those pictures and a great soundtrack. What's the song used?          I'm at the point where I'm deciding if I should start with Eternum or play other games first. I love saving the best for last and I think if I play Eternum now, I'll have such high expectations from other AVNs which might not satisfy that itch. Will gladly support you on patreon if only our exchange rate weren't that high but we'll see in the future. Anyway please continue making these games!!!

probably one of the best games i played, it's definitely on my top 10. i just love the harmony between the plot and the other "plot", it's perfectly balanced. Overall a deserved 5 star rating. looking forward for updates, i'll play eternum for a while

Absolutely amazing story and game, both intrigging, fun, romantic and sexual. 10/10 definitely. One little question: how to get a scene with a teacher during her wedding? Unlocked all scenes except these.

i want to download this game on the pc app but its not letting m

Hi everyone just finished the whole game in one go.

I ain't gonna lie: I fuckin loved it!!

Btw I tried my best to reach 40 out of 40 with Judie but I finished the game with 38 out of 40.

Is there a list anywhere with the r8 options for each character?

The scene with James at the toilet while he dates Judie is so much more fun, if you got the psychopath ending with Dr. Monroe. Too bad we are not able to prank him with a hand grenade in the toilet tank. xD

I played this game many months ago, early this year, and it is one of my three favorite adult visual novels ever made.  Once in a lifetime, Eternum, both by Caribdis, and Everlasting Summer, the first visual novel I ever played through.  Caribdis is an absolute mastermind at this, Their stories combine mystery, comedy, action, and sexuality in such a flawless fashion as to be absolutely awe inspiring.  In fact no amount of praise can ever fully describe just how amazing Caribdis IS at producing adult visual novels.  I wanted to download and play Once In A Lifetime again, just having finished Eternum thus far a few days ago, but am unable to because my internet is very bad and sometimes unstable.  Trying to download without some kind of download manager usually results in 'network failure' errors, and am unable to resume after that.  I have the app for this website but OIAL is apparently to large to host on here.  I was wanting to ask Caribdis if OIAL is available to download by bittorrent anywhere.  Anyhow again thank you Caribdis for the outstanding and as I said before indescribably wonderful work you have done on OIAL and Eternum.  And I hope you keep making more AVNs after Eternum is finished.

dang, Lauren BEST GIRL, and also, love that BlackMetal Riffs in that scene with lauren at park and the travel to village🤘🤘🤘 Thanks Caribdis, this VN has been one of the best games i've ever played, if someone ever asked me of a good VN game, i'd say Caribdis without hesitation, the character developments are extraordinary along with Eternum, LAUREN BEST GIRL

Completed the game in one sitting, it's beautiful. I was surprised at how much character and story development there was along side the comedic factor and the horror part it had. I highly recommend this game, awesome!

I've played for about an hour and still haven't heard any music in the game, only the sound effects. The main menu theme does play.
Is this normal or something's wrong with my game?

Looking forward to the completion of Eternum, if this game is any indicator then we will have another masterpiece on our hands.

Is this game 100% finished? I don't see anything new from last year.

Damn that was really good, very well done!

can you download this game on an apple phone? if yes which one

the history I saw here made me fear that the creator would have only this masterpiece done, so I'm glad to see the diamond hands keep going on Eternum, many come to see if is just more one explicit game, but leave knowing that a game with deep history and well-done characters makes this genre far better... you start to look with less value to games poor or lazy written after that.

You know this is the best avn in history ever and best thing is it is completed which gives satisfaction and joy and sadness that it ends,it has thousands reason to play for but u will giv you best one,play it because it has stabby mike the best side character ever scene in any movie,series,drama,shows, webseries,game,vn,irl no match for tht guy you will love him more than this avn and girls for sure,but don't expect some bromance haha.

Hey Caribdis! I am  loving the game so far, but I have a bit of a conundrum.  It's been a while since I played the game last and I can't remember if I have impregnation on or not. Would you mind sharing with me, the file I need to look at to see if this is true?

Thank you either way!

Made an account just to comment how much I loved this Game and Eternum. A lot of These horny games are cool and all but with Once in A Lifetime and Eternum I've found myself actually having fun, Enjoying myself even when there's no sex happening on screen. I can't give a higher recommendation to any game. 6/5 stars. 

    Man how can I start this... 
    I read novels a lot, yet not really a fan of visual novels in the past, especially English isn't even my mother language. I'm from Taiwan; We speak Mandarin.
    Yet totally changed this June.
    Starting from playing Waifu Academy a little bit; then truly got interested in VN after finding My Bully is My Lover; and, now there's Eternum and Once in a Lifetime.

    I'll say Eternum is kind of like a full upgraded version of Once in a Lifetime, yet OIAL is already etertaining enough, especially it's the first complete VN game for me. It's an overwhelmingly good experience.
    Great experience here even for a foreigner here. I already saw lots of praises and cheers in the comments below, but hey, maybe a big praise from someone who lives in a foreign country that you may even hardly knew can somehow cheer you or inspired you a little bit more.

    I truly love the game, love the story. Thank you Caribdis.
    Bro I even create the account for leaving my comment here LUL.

Why does my game end after the Japanese game show?

I just finish playing and God I loved every second, it's not just your typical sex game, is so much fun to play and see every posible outcome, the parts where you can "play" those multi answer games are the most fun i ever had in a visual novel and the story is so original and fresh, not your typical "I just move in with my new family and need to adapt to it."

Quick question. I followed the paths for every girl and finished but is there not a way to take all of them on the airplane

Chang is Eternum's Stabby Mike

Alright, comprehensive review time motherfuckers:

Jesus Christ where do i even start? 

First an foremost, if your looking at the itch.io page wondering whether or not you should download the game, DO IT

Once in a lifetime is one of the most complete adult games I've ever played before, its got everything. Heartwarming romance, great sex scenes, an amazing sense of humor, genuinely scary horror sections, and quite literally the best plot I've ever seen before in a visual novel.

Its not just your typical "Boy wakes up and builds a harem in a week" type games, its clear how much effort was put into the story and background of the world, and the multiple endings are all great. Except for the secret one. That one still eludes me xD

Eternum is gonna be in development for at least a few more years, having played 0.3 to completion and having 0.4 ready to go after i post this  i am very excited as to what will happen next!

I really do hope there is a least a little bit of crossover between the two games, maybe the OIAL MC could tutor Eternum MC in how to handle having a harem, and maybe a little bit on the occult too.

God bless you Caribdis you glorious bastard, and I am so excited to see what you come up with next!

This game is not bad, but I still think the other game Eternum is much better than this one. Not only the graphics, but also the stories perform more excellent. Honestly, some of the girl's routes like Jas and Iris didn't impress me, in my opinion the main character doesn't show enough charming part on those routes, those girls just surrender because of his magic dick, which give me a feel that those part are not well designed. But anyway, most of the stories like Carla, Lauren and Judie's parts were amazing, it worth having a try before the update of Eternum 0.5.

Well, i finally finished both Eternum 0.4 and once in a lifetime yesterday, btw i found out in another page that this one existed, so while waiting for Eternum why wouldn't I give it a try?  And I must say that it was a REALLY good decision, you're a genius, dude I wish I had discovered this game much earlier,  but still, it was amazing, it completely surprised me, i don't usually play games like this, I'm not really a visual novel enjoyer... But i did enjoyed both a lot, I'm looking forward to support you, because your work deserves it as much as you. Meanwhile, i'll wait for the next Eternum update, which I'm sure that'll be amazing. Thank you man, this was an incredible game.

well i was waiting for eternum 0.4 to get released but after i downloaded eternum 0.4 i found that you have another game maaan i wish i found this sooner while waiting for new eternum update, is this game finished btw? so i dont need to wait for new updates :P and cant wait

Came here and played this game immediately after finishing Eternum 0.4. because good lord the quality that Caribdis puts out is bar none. The story, the characters, and everything in between is so damn good. The choices are legitimate and the replay value on this is just another checkmark to add to the list of why this is a top-tier VN. If you want a VN with a damn good story and meaningful choices on top of the porn? Well just click the damn download button already. And then go and play Eternum too because if you liked this? Holy fucking damn will you like Eternum.

Also Lauren, Aiko, and Jasmine best girls.

Also Stabby Mike best character and I will not be convinced otherwise!

how do you even beat tom at the party?!? i keep trying all the numbers i can use but nothing works. what do i have to do to beat this guy

Haven't started the game yet just wanted to know what the starting menu song is! It goes hard

Your amazing! I played all of .3, since the .4 was coming out tmrw I figured it seemed fitting to finish the first game beforehand, easily one of the best VN I've played in my life, and that is saying something! Especially among visual novels, I hope you continue to make incredible games in the future! also I assume the reference to cults in Eternum is a hint at this game? Great job incorporating hints at what is coming next, has happend previously. This game truly is something that only happens, Once in a lifetime. Just like Michael Stabb said!

How do you win in the gameshow to go to Japan?

Thanks for the game ! 

Maybe because I play in a TV, but I often find text hard to read. Would love option to toggle a textbox, or change font color/size. One example where I struggle in pic attached, try zooming out to replicate.

So caribdis, bro i was playing eternum and i finished 0.3 and was like this was good does he have another one? well what do you know he does and man this one left me speechless as well, i cant wait for what you have in store for us later, 10/10

This game is awesome, I finished the good ending and I got emotional, I got the secret ending and also emotional but its kind of weird that I feel sad/bad about that one?XD
