Fun idea! I like the art style a lot.
I first started playing without reading "how to play" and couldn't understand why I was dying. Once I've read the instruction it was clear. I feel like the mechanic is so simple it could've been explained by itself. There is a cool "red vision" effect when hiding. If it was shown for a brief moment when I'm not hiding instead of instantly loosing it would be easier to understand.
But this is just a nitpick. It's a fun game, good job!
