Cool game, but there is always room for improvement.
1) This game really needed checkpoints. After I died, I really didn't want to go back to the start. And do the whole thing over again.
2) With some of the fences, my robots would just fall through the fence. Sometimes they died, other times they just kept moving on air.
Other than that though, great submission. I really liked the sfx, and the music was good, the art, while simple, was well done (reminded me of Undertale in that regard) and the theme was used well. I liked it!
