It's very pretty...
Apart from the very pretty graphics (the menu not included...) the game was terrible. There is no jump function, or complicated terrain. It's just a straight line with zombies, and then some sort of invincible puking tank. You just go to a zone, hold down ctrl, wait, go to the next zone, and repeat. When I finally got to the tank boss thing, it turned out to be a game of standing far away and holding down alt, thus bombarding it with missiles. Could have at least made the tank shoot at me instead of just having dozens of zombie pukes spawn from the middle of the sprite.
After shooting the tank for quite some time, the game apparently got as bored as I did because it suddenly quit back to the menu. Perhaps I hit an odd key combo or something in an attempt to find something that might cause something to happen.
If you want to get stuck on the tank faster you can merely run past all of the zombies. Bit of a gameplay problem there.
The sounds were fine, except not all the effects had sounds scripted to them and the volume was odd. My machinegun is silent, and rockets are quieter than a zombie up-chucking somehow.
Overall, the game needs to be turned into an actual game rather than an interactive slideshow of a robot shooting zombies. Add things like jumping, interactive levels, multiple paths, or even monsters that don't just shamble at you and die.
