A downloadable game for Windows, macOS, Linux, and Android

This is the uncensored final demo of To Trust an Incubus with voices!  The full game is being sold on Itch through partners who will not allow adult content, so it is censored with an easy off-site patch to remove censoring. GRAB THE FULL GAME HERE!


Temp worker Kenta is locked in a lab with Four SEXY Incubi from another dimension! A gay sci-fi yaoi/bara dating sim for ADULTS ONLY!

Kenta, a temp worker, gets a job in a lab that's holding four muscly incubi aliens in quarantine. They came through Professor Raiden's interdimensional portal like several other beings who visited Japan before them.

Past interdimensional visitors have warned Professor Raiden about aliens that look just like these ones. They might be ravagers who are scouting Earth to plunder it.

The top linguist working for the lab can barely communicate with the incubi. He's figured out they need to bond with someone in order to learn their language.

Will Kenta be the one to bond with the incubi? And if so, will he be able to figure out if they're the evil ravagers or some other benign race?

  • A Dynamic, Story-driven Dating Sim with over 150,000 Words
  • Four Routes, 35 Endings 
  • 24 Original Music Tracks
  • Full Voice Acting from Top Anime and Game Voice Actors
  • Twosome and Threesome Romance Options
  • All Characters Versatile
  • Over 200 Gorgeous CGs
  • Three Unique Mini-Games
  • An Intricate 'Choices Matter' Stats System

Will the incubi stay in our world? Will Kenta get a permanent job? Make the right choices to get happily-ever-afters for everyone's endings, or the wrong choices for some magnificently effed-up endings. 

Sexually explicit art is censored with chibi stickers. There is an off-site patch to remove the censoring for the full game.

Kenta saw the incubi in the news and was fascinated by them. He can't believe he'll get to work with the amazing beings. He's been a temp worker for a while and hopes he can impress Professor Raiden so he'll have a permanent job. Voiced by Kiba Walker (Zoolaplex, Seiyuu Danshi).

The interdimensional portal is the result of a lifetime of hard work and dedication by Professor Raiden. He gave up on any chance of serious romance to focus 100% on his discoveries. Voiced by Nathan Matthews (Yaoikuza, Tender Master).

Arata has been Raiden's faithful assistant for years. He considers Raiden his senpai...and wonders when he'll notice him. Voiced by Steve Warky Nunez (Final Fantasy XIV: A Realm Reborn, Heroes of Newerth, Yandere Simulator)

Devi came through the interdimensional portal with his leader Vald. Little is known about the incubus, but he seems kind, warm, and gentle. Voiced by Reece Bridger (Fare Thee Well, Bulletville).

Vald came through the interdimensional portal with his subordinate Devi. He gives off the cool air of a born leader--or an evil general? Voiced by Terrance Drye (Fare Thee Well, The Braggers Club).

Saji came through the interdimensional portal a week after Vald and Devi arrived. Though quiet and withdrawn it appears like he's running from someone. Voiced by John Masterson.

Harsi came through the interdimensional portal the day after Saji arrived and seems to be looking for him. This rough and tough incubus is nothing but trouble! Voiced by Sean Chiplock (Full Service, Persona 5, Danganronpa V3, Legend of Zelda: Breath of the Wild).

Hey...can someone please help me :(...when i try to open the game it says Scripterror: Name (u'/home/tom/ab/renpy/renpy/common/000atl.rpy', 1504313599, 0) is defined twice, at renpy/common/000atl.rpy:25 and renpy/common/000atl_1.rpyc:25...thanks in advance :)

Please delete and reinstall

When will the game release on itch.io? I am saving my steam code I got for backing so I can get it on itch since it'll be DRM-free


February or sooner. We are working this out.

Awesome! Then I can keep waiting. Thanks for the reply :)

hey guys, loved the game. I got it on steam. i got a good ending with saji but not the others. i bought the cheat sheet, but dont know where it is or how to open it or work it! help!!

nevermind! i went to the steam page for the cheat map and read the directions!! lol, sorry

I'm sorry, ShadowLamb!!  They don't make it easy.  We put instructions on the description, but it's still difficult to find.  :(

Harsi, my true love.

KAY SO!!! Will the Steam release be at midnight exactly?!?!! 

It's out now!  https://store.steampowered.com/app/825300/To_Trust_an_Incubus/

I. Am. So. Impressed.

Seriously, I've been with you guys since MDL and this game is fucking BEAUTIFUL. Gorgeous art, voice acting on POINT, MC is realistic and relatable and EACH route got to me. I fell in love with Devi and Harsi, Vald and Saji. ...For anyone on the fence about buying it, let me know and I'll buy it FOR YOU. It's just THAT GOOD. โ™ช

Keep it up, YPress. You guys make solid games and have a lovely thing going on with lots of love and support from us fans~

@Veritas, I mean I have been wanting to get it for some time now, but I don't have the money to get it, I played the demo a few times  and gone through all the routes they have there and enjoyed them all so much, idk if your offer still stands, or how it'd work even if it does still stand.

Can you jog our memory about what offer you're talking about?

Will we be able to buy it here for pc at the same time it become available on steam? If not, will it be available for purchase here at a later date? I'm not a big fan of steam and prefer to purchase on itch.io when I can.

We will definitely have an Itch release in the future.  Possibly early next year.

$19.99 :)  Coming Nov. 23rd to Steam! <3

Is this just the steam version or will the phone version be available here or at a later date? 

Just Steam.




when is the full version coming out


November 23rd!!!!



Can't wait for the full game!  Like the demo very much! :D

I wish there was more to the demo


HONEY if you ask me ther's plenty to the demo to know how AMAZING this game will be!

could someone please tell me how to run the file? I'm not really good with technical things so it'd be real helpful if someone could explain it to me. I really want to play this game~!! TT


It's about time that someone makes a smutty game like this!! I LOVE IT...I like that the MC is top/bottom depending on which character he interacts with, although it would be nice to be able to have both positions available for all characters. Seriously appreciate you guys and the top quality art work and script you have put together. I'm soooo excited to see how it turns out, please don't make us wait too long :*)

i love this demo game, they all r so sexy and hot

Deleted 2 years ago

Of course! That's usually how it goes so I am pretty sure it will also be the case with this game.


It's really great. When is the full game gonna be released? :)

Wooow. how did you make this game? It is really amazing u know 

Can u please see my game too, 


(1 edit) (+1)

I don't think I ever commented here yet. That is a tragedy in itself.

But basically, I covered the game and it was a load of fun! Even beyond my constraints. (or maybe especially because of). And condragulations to the team for making their kickstarter a success!

I also have the uncensored goodies in my blog, for anyone interested. But yeah, download the demo for yourself and make your own opinions. I highly recommend the game if you like rippled guys and some PWP.

how does one see these uncensored goodies?

https://ypressgames.com/2018/11/02/patch-to-remove-censoring-from-to-trust-an-incubus/  Grab the patch!

Congrats on your Kickstarter! I feel bad that I couldn't donate, but I'll buy the full game when it's out for sure.



how do u download the game???

It's still in development. You can play the demo, but the game is not available yet.

awesome demo! those incubi are really hot! especially Harsi <3. and it's just bara enough to enjoy beautiful males, but yeah, no need for too much hair XD - it's perfect. nice UI, good plot. love the idea of a moresome too! waiting impatiently for it to be out!

i saw sth in the previous comments.. not sure. you're planning to also release the game for sale right? like, on steam (with patch) or here? i can't back it on KS, first i'm really broke until the end of april (by then the KS is over), second i don't really like to spread data at too many places.. but on steam or even here, i'd buy it immediately ^^

the character designs look like bishounen yaoi than bara to me O.o 

super hot

I loved it!!!!!!!!!! Will the characters be versatile? because I would love that

Cool game! The art is so beautiful!! Amazing! I kinda miss having the ability to choose. I know that this is a demo, so it isn't fully done yet, but I hope that you might add choices later on. I think it would help make the game longer to play. It seemed like it all happened so fast, but it was really good, even so! I look forward to the final result.


you need to download the itch.io app in order to play the demo

Hihi for some reason clicking the download button does nothing. Really want to try out the demo though. Help~~

im having the same problem 

(1 edit)

i cant downlode the demo =[

but i wanna play it as it looks amazing 


could u make a zip-folder for this pleze


Hi!  The Mac and Win versions are in zip folders.  You can't zip Android or Linux files.

ok thanks =D


This look very amazing and I'm happy the someone making a incubus game.

I have been waiting for it ^_^

as someone who has an unhealthy obsession with all things supernatural and especially incubi this God damn game is just... Perfect.  Not to mention the story has got me super interested.  The cute guys and sexy times are a plus but even without them I'd be interested in the story. I can not wait for the full thing. 

Just wondering,  as someone that's awful at these things sorta,  will there be a guide like after it's complete? 

Thank you!  We're glad you are into it!  There is a cheat map as one of the perks on our Kickstarter.  It goes live Monday!!!  This game will only get made if we get funding...but we think we have a good chance!

When the full game come out will it be available to buy online and download?

If we get funding, backers will get their copies in November 2018!!

Are the copies digital? And if they are will we get them in like an email? Thanks.


There's digital and physical versions of the game available for perks.  We will be deciding the best way to distribute digital copies later on, but it would be much too large for an email probably.  :)
