Incredible game, felt very cohesive and you got a lot out of the main mechanic. Well done!
Only minor gripes I have are that I would have liked some kind of cool-down indicator for gravity switching (something analogous to a bar, but ideally more integrated into the art style), and a way to zoom out to see the entire level (the telescope-like ability is a step in the right direction, but would often still leave a lot obscured).
Otherwise this was awesome. The puzzles were a lot of fun, the writing was funny very serious, the visuals are really nice, and the music is great.
