I was getting ready to write this off as a basic bottom-to-top navigator, but then ran into a dead-end, used a time crystal, and was exposed to the "rewind mechanic"—which I thought was innovative (at least in the game jam scene).
Happened once where I collecting a second time crystal in one scene, the plane increased its speed, but this coincided with a massive lag that had me crash into an avoidable wall (this was on the web version, though).
Ended my playthrough after the twelfth level, as without any progression feedback, presumed it was endless, but I liked this idea a lot. Also the UI sidebar that tells you how far into the level you are. Little touches make all the difference. :)
