I really like this interpretation of the theme. There have been a few games where the world grows or shrinks based on your movement, but this is the first time I've felt that it integrated well into the gameplay. The level design is good too. I didn't realize that the robot could collect the keys for me for a long time though. As for improvements, it would have been nice to see art for the rescaling blocks. I also would have liked to have a better sense for whether a jump is possible or not (our game also has this problem). Other than that seems good.
