I got to level 4. I is pretty fun IMHO, I really like that the zombies uses urns as shields. Pumpkins are a neat enemy, you do not have to kill them but can instead avoid them. The archer guy nor the font used does not really fit the art style of the game.

The backgrounds kinda hurt my eyes and its too easy. It's also kinda weird that the player is a vector graphic and nothing else is.

Horribly unoptimized in some areas, it's annoying to use the mouse with the arrow keys, graphics feel mismatched and overall this isn't really fun at all.
