First of all, I have to say that I thought the game was incredibly good. It walks a very fine line between originality and the grotesque, and I think that combination gives it a lot of personality.
Unfortunately, the game froze on several of my attempts while I was editing the faces. I couldn’t determine exactly what caused it or when it happened, since it occurred across multiple playthroughs, including once during the initial tutorial. That said, I completely understand that a game jam project can’t always be fully polished.
As a suggestion, I think it would help to have a little more time to edit the faces. The controls require a fair amount of precision, and with the current timer it can be difficult to react before time runs out. I understand that this sense of pressure is an intentional design choice, and I think it works well. Even so, giving the player a few extra seconds would likely preserve that feeling of urgency while allowing a bit more room to interact with the mechanic.
Great job, and congratulations on the game!
