I like the idea you have going on here where you have to purposely smash yourself into blocks in order to break them, but I feel like the character you have doesn't match the gameplay. The character is just some normal explorer person who turns into a pool of blood when they die, so it feels weird that blocks get destroyed when they get squished into a wall. I realize this is just a jam game, but if you decide to expand upon this, maybe it would make more sense if you played as like a volatile exploding robot or magical statue? Or even just a normal guy with dynamite strapped to his chest, idk.
