The game was really good. I've enjoyed the playing, it wasn't very hard. First when I've started it the zombies has bitten my ass off and rest of the game I was playing with 10% of health ;). But dude under me is right - more health packs would be nice.

Very fun game, really good too. It's damn hard, however.
I agree with the others: multiple difficutlies would be nice, as would be an increased health drop rate in normal. And that thrown stuff is insane. No zombie would throw stuff, they just shamble forwards. And it does way too much damage for a rock. Stupid thing, really frustrating.
--> More health pickups and no thrown stuff makes this a 9 easily.

It's a great game man. Don't add health, it makes the game more challenging. I'm not just saying this because I'm now #1 in kills.

Not a bad game, but I think there are some things that should be changed. Most people want more health or more health powerups, and that's probably a good idea. However, there are a few people who want the health to stay the same, for the challenge it makes.

I suggest that you add multiple difficulty modes, with the amount of health, damage done, and powerups changing by level.
I also definitely agree with the suggestion to remove the thrown stuff. Would a zombie really be smart enough to try something like that? Besides, its annoying. It could be something for a hard difficulty, though.

Finally, I would like some further explanation of how things work in the game, more than just the controls. I've figured out most of this stuff, but it would be helpful to have an explanation of what the different powerups and weapons do, what the different upgrades do, and what the different zombie types are (and what are those other things, bats?).

None of these complaints are enough to detract much from the gameplay, so it is still fun, but you could make changes to make the game easier for first-time players.

Its the only thing that makes the game a challenge . Good game
