This is very impressive! A gameboy game!? Really well-made, I like the art direction, music is catchy and gameplay is simple, but the puzzles can become difficult with time. Loved it! One thing though is the vision of the player's robot, sometimes (noticed it on one of the first levels) if you are further than a few blocks away from the robot(they are still in the line of sight), no connection occurs, and sometimes it does occur.. I would maybe add some visual indicator, though not very sure about it xd. But this is just nitpicking, other than that - loved it!
