That was quite a fun game! Like most game jam stuff it definitely lacks polish, but so does almost every game jam game (for pete's sake my game doesn't even have sound). I think you've got a great core mechanic in the puzzle/stealth combo and the assimilation ability, you could definitely develop it further if you want to. Given that your player character is an ooze-like thing there are a ton of different ways you could expand on this, maybe with shape changing abilities or being able to mimic furniture? Although you kind of already have this with the hiding in desks.
All in all, great submission folks, I hope to see you at one of these again!
