Liked the robots having visual feedback when trying to commit a movement they couldn't do - a nice bit of juice and feedback.
Having controls so visible at the start and throughout was very handy.
The puzzles were just challenging enough to feel good about finishing them but not so impossible someone might need a walkthrough. They all made sense. except 5 might be my puzzle solving roof lol.
I dont really have any suggestions for this one - the mechanics are cool, the art is nice, there's good feedback the puzzles seem well designed and the inclusion of a visible control scheme is welcome.
