Great game! (I'm writing in English because I believe it's your primary language, forgive me if it's not). The concept is certainly very original. I would have never imagined it. The game is fun and provides entertainment for a while. I like the detail of being able to see the insects approaching at the edge of the screen. It's a small detail, but I find it essential to know if your beer is in danger.
I would have liked the game to explain the main mechanic a little at the beginning, but since it's simple, you can easily figure it out. I think it's awesome that you made a game like this in such a short time, focusing on creating something fun and replayable. Good job!
