Robot Infiltration by unnamed1334
The robot army is attacking and you have to stop them.
However, the army to too strong to take on directly and will repair the damage you do.

The robot army does have one weakness; the robots need a constant supply of power to keep running. Taking out the towers will leave the robots powerless.
Taking out the generator will stop the robot army.
Controls:
W-A-S-D to move
Left mouse button to shoot.
Right mouse button to look around.
Hints:
The robots are not very smart. If they lose sight of you, they will only look at the last place they saw you.
Some doors are powered by a distant tower.
The room in the back contains the factory. Take out the tower near it and the robot army wont be able to make any replacements.

Update:
8/2 - Added a WebGL version of the game.

Also there is funny and challenging gameplay)
I liked the art (although I get the impression you had plans to do more with graphics, it still looks nice :-) ).
The controls were simple and straightforward, also good. I could get playing without too much trouble.
I felt a lot like the combat was a war of attrition. The robots seemed to take a long time to bring down even on the easier difficulties. I found I wanted to just run past them altogether because I had a hard time liking the combat. The difficulty, as far as I could tell, affected firing rates and maybe my robot's health... but I can't be too sure.
The health bars (energy?) were small so it was hard to see what was going on.
I was confused a bit by the staircase. All the walls are represented by black lines, so when I first saw the staircase (also represented by black lines) I thought it was just part of the wall. Eventually I figured it out though.
Overall I agree with other posters above that you should be proud of this game, it is indeed an accomplishment!
