Fun little game :)
I like interacting is with the "E" key, so I kept throwing my pants away every time I tried to flick a switch, maybe swapping the "Q" and "E" would be nice.
The puzzles are nice, but not to challenging, but they take a bit of time because the robot is kinda slow. Maybe increasing the move speed of the robot and the pants and then placing more fences to help line the shots better, because the acid is unforgiving.
I had fun, and the game is pretty good job :)
