This is short and simple, but it works! I would say that there should be a little more work behind logically releasing new zombies. The game's randomness makes it almost impossible to catch up over time as it is, but that's what post-jam polish is for. The animations are really good! I was impressed :)

Oh, also, even though your link points to your source code as well, you should have a second link. It can link to the same place (see my entry for an example). People may be reluctant to rate a compo game that doesn't have a source code link!

Thanks for playing! p.s this is my frist ludum dare ;)

Nice little game! Animations and music are good. I would recommend adding a score system and maybe some upgrades because after some time it is almost impossible to advance any further in the game. Overall good job!
