Seems like a really cool game! I loved the feeling I got when entering a new area and looking around. The feelings of isolation while exploring massive, wondrous, and magical places was awesome.
Unfortunately, I wasn't able to figure out how to beat the air world. I gave it a lot of goes and was able to extinguish 2 beacons, but after dying like 20 times trying to jump to different places and taking a long time looking down around the edges of the walkable area, I eventually gave up. It made me sad because I wanted to experience more cool and wondrous places you guys had created.
Good luck with the jam! I enjoyed what I was able to experience in it.
