The graphics are good. Everything else about this game is wrong.
1- Your powerup structure just falls apart at the end. I got 14 character upgrades and several weapons at the end of a single round, after 2 unsuccessful prior attempts.
2- The game has only one level background. Ugh. If you're expecting players to play many levels, some variety would be nice.
3- The enemies piss me off, for some reason. Not the challenge, but the repetitive abilities. And the suicide enemy... it's not cute that you dressed him to look that way, it's just a crummy (albeit veiled) jab at Muslims.
The voices make it a little tough to tell who's falling when you're matching. I keep looking up for soldier bodies and can't find them- maybe it's because I'm just so awesome at this ^_^
But seriously, can you make the undead sound more undead-ier?
