Is it possible to get all the robots with only two keys? This is good as a puzzle concept but I couldn't tell if it was actually completable. The game also really needs audio, even a basic shooting sound would have gone a long way.
What is the purpose of the lights? You're in a dark space which would suggest some sort of sneaking around, but you and the enemies have lights.
Lastly, there is no consistency with the fonts. There area multiple different sizes, some have a capitalised letter, some don't, maybe I'm being picky but that's the first thing I noticed.
Good concept, not really sure on the direction.
