Wow.

This game is very nice, i like a lot the art, the music, the menu...
But i agree on the gameplay problems. I tried some times, and i didn't manage to survive more than 2 minutes.
-The idea to make zombies invisible when not aimed is nice, but makes the game a lot difficult because you can't see most of the enemies.
-I don't know if i'm doing something wrong, but the weapon takes a lot of time to reload, enough to take half-life damage every time i kill two zombies.
-Zombies are too quick, too aggressive or too strong. I would suggest you to lower at least one of these three.

Please keep making flash (w/ an update on this game, or other flashes), because i like your style. :D

Really well done, except for gameplay

I can see you put a really long time in this, but there are some critical problems with the gameplay, ranging from the number and position of zombie spawns, the amount of ammo given to the player, the speed and attack power of the player, and overall progression of the game.
Also, there is no incentive to make you play more once you've died twice, it's not even fun.

I do like it don't get me wrong

I love the idea and the art. But the character moves SOOOOO slow and the controls are really clumsy. Plus it needs a bigger level.
