That was great! The sprites and the animations are beautiful and full of character, especially how the character respawns and picks itself back up! And of course, the SUCK!
I think it is a little bit too hard. To make the game even better, maybe give us more tools to deal with the enraged zombies, and add some pause time after the zombies spawn to prevent them from attacking immediately. Too often I was using the SUCK and a zombie spawn right behind my back and got me.
Great game! great animation! Great job!
