Very interesting, some instructions would be nice, especially regarding the keyboard element and how it works. I was super confused until I paid more attention to the intro cutscene, which is surprisingly nice graphically. I think the idea that touching a propeller on the side of a 'ring' can disable them, and that messes with your movement is cool. Kind of reminds me of a game called ragdoll avalanche 3 in that sense.
I saw the info about the keyboard, and was able to use it successfully once anyway, which was very helpful for that run. I imagine if you know the keyboard controls well, you can do a lot with them.
The in-game joystick was cool in that you can get some fine movement control from it, at least in theory. It's something you have to focus on though, at least if you're using a mouse.
Visually, a small touch of angle on the rings might have been good to help readability and help show where the edges are. It certainly adds cost to losing lives, mechanically it's a bit rough because of the negative snowball effect though the keyboard system is at least capable of countering that to some extent though.
