Graphics are nice, controls are smooth, gameplay solid and there is also reasonable amount of variety, so overall I'd say this is a pretty nice game that also captures the theme well. I would love to see powerups standing out a bit more and also giving more noticeable effects, as right now they're pretty hard to get and not as rewarding. Also, I really liked the visual effect of the curse and how you turn into a zombie when you lose.
oh, and one more thing: I think game size might be reduced for sure.
