Not bad, could be better
Good Game really, a few little things that it could've done with:
Blood
More music that's less repetitive
the Splash Damage from the shots means that you can be injured if your standing next to a wall on the final stage
Improvements on controls:
The aiming should rotate the whole person rather than the gun, and then you can map the left and right keys for strafing.
A bit shabby.
The collision detection is extremely poor, and movement relative to the direction you are facing makes it feel confusing and unresponsive. In addition, this game is a near clone of the zombie top-down shooter that came out last week. Also, once the level is cleared it takes forever to reach the next level sign. If the next level requires loading time you might as well just make it automatically level once all the enemies are dead.
better
good game but a bit small and i didnt like the others constantly shooting, last bits a bit hard, need more hit points sound and music loops to much but it loads fast thats good
glitch found
i found a glitch on the final level if you go around the building to the right side against the edge of the game it sends you back to the 4th level.
A real game
I'll play this one more than once. It's simple enough to be possible at lower levels and has intuitive controls. Any improvements beyond bugfixing are gravy.
