The mechanic is really fun! it reminds me of one world of Braid, where you need to collab with your shadow to pass the level. The sound effect and level entering is also fun, but somehow becomes too intuitive to me that I directly entered level 3 without been through level 2 so I was never aware of the rule that the head needs to be pushed towards the body in order to get the robot moves haha so I've been struggling with a upside-down robot a bit. But it definitely is a great game with great chemistry effect by simple rules. I also appreciate the stopping blocks that serve as a buffer to adjust the position, which effectively manages the difficulty curve. This is a great game!
