I liked this game! I feel like there are a few areas where the experience could be improved: an indicator that says when I've actually grabbed the wall (since the "launch" bar fills up even if I haven't), being able to control the direction of the wiggle (e.g., call it a little rechargeable RCS backpack), and highlighting which objects in the foreground/background are interactable. Whizzing around the rooms and trying to grab the batteries at a high speed was a fun challenge, and it would be nice to have a little more control, especially since the rooms are much bigger than one screen.
I think this would work very well as a metroidvania-type game, where you do some platforming then switch to 0G to solve a puzzle, then switch back. It might also help give the levels more interesting shapes.
