This is great. I love that it's kind of a de-make, for two reasons: first, it meant you offered something really unique to the game you're riffing off; second, it's a great way to scale your efforts into a jam-sized jam.
The flying and gravity mechanics are just fun, which is exactly what you want. I would echo the comments that the game would benefit from a better line-of-sight on progress or end goals... there were definitely moments where I wasn't sure what was needed from me. But I figured it out, I finished the game, and I had a good time doing so.
Oh, and it almost goes without saying that this looks great, too. Very Sokpop, but with your own spin. Great work.
