Good concept for a game. It's like a physics-based version of Bomberman. I like the art, especially the power-ups.. I like the risk-reward of risking your life to push the bombs towards other players, though, I wish there was a way to hit them to force them around a little faster. Jumping seems useless as far as I can tell. Maybe you could make use of the jump by having a way to jump over explosions with good timing or maybe adding some verticality to the levels..
I could see this being expanded into a fun party game. Nice job!
