I beat the game, found it fun and not super challenging. Although I found a bug in the last level where crashing into a box with the rocket ability while you have the grabber ability causes the line from the latter to stay on screen which reverts abilities to the sides of your character when intersecting the line. This makes the level harder than intended.
I only encountered this issue in the top 2 rows of the last level but might not be exclusive to that, so I had to make sure the line was in the top row to be able to successfully complete the level.
