Good start! To really polish it up, I'd suggest you adjust the walking animation speed so that the robot's stride length matches his movement.
Maybe add some background visuals or variety in blocks, because right now it is very plain looking.
It also needs to be easier to press the laser buttons, because right now it takes me 10 tries to get the robot's position to line up correctly to hit the button.
Lastly I'd strongly suggest some more variety in the puzzles. All of them right now are little more than trial and error, which is very frustrating given the relatively slow pace of the game.
