(I am now in a rush to test as many games as possible to help, so please do not mind the cursory reviewing style.)
Semi-on-the-fly remarks:
controls ARE layout-independent!! :D (I have an AZERTY keyboard)
P works for pause; I advise writing it somewhere (on the game page, and in the game when you have the chance again)
Not obvious to get where you can get detected or not: is it room-wise? Also, farted (in a corridor, I think), then went up, and got detected while not farting! ._. So, is there some farting DELAY around which you can still get detected? Ah, maybe if you are still in a fart-full room WHEN a suspicious person ENTERS?
Oh, did not notice "and broke up with you"! XD And the gloomy music continues! Well, that escalated quickly. ;)
I think adding some kind of counter/statistic could help the player knowing how he fares, and get a high score.
Takeaway: stealth game with a (stinking) twist! XD Funny and effective; even the music is stealthy, which is fitting. Sound effects are great, the main mechanic is simple and clear, the UI indications and controls are clear. :) The only two things I could really reproach the game for would be that knowing when you can get detected is not really obvious (some dynamics area indications could help? The farting fumes do not tell everything, apparently), and that some other mechanics would have kept interest in the longer run.
I see on the game page that you went for originality (contradicting both of two Brackeys’s video pieces of advice, saying that the first idea is the best and that you should not try to invent a new original concept XD) and learnt from your previous game jam to go for simplicity and efficiency: a lesson well applied, well done! :) Ironically, I wish you had extended the scope of the game a little, but it is already pleasing as it is.
PS: I feel bad for having to compare long games (such as PLAT Inc., NeededTwo, or Cubemunity) with shorter ones as this one, because I feel you can get better judgement with less content, since length or lifespan is not a criterion. This is not a criticism against shorter games, but an intrinsic problem when allowing such a wide variety in games.
