Great Game

I got 446 Kills On My first shot, some good ideas would be upgrades you can buy with your kills.

Besides that, I love it!

Has potential.

Pros:
* Simple controls
* Clear objective
* Not impossible

Cons:
* No sounds
* No pause button
* Only one death pose
* Difficulty increases are too subtle

Possible improvements:
* Appropriate sounds
* Pause feature
* Extra death poses
* Magazine limit with reload feature
* Increased difficulty jumps

Its an alright game

Quite a simple game but maybe though, if you add these suggestions, it can make the game better:
Maybe instead of increasing the difficulty as you move on, you should be able to select the mode that you want to play.
An upgrade shop can be a nice addition too. It would sell better quality equipment like better guns, a defense wall, extra turrets and stuff like that.
I'd say just keep working on it and release the next version with more features.

its ok

i aggree with the clicking and maybe you could make it alittle harder. -2 stars for graphics

clicking

make it so you can hold mouse button instead of clicking constantly
