This was a lot of fun to play! the controls feel good and the movement mechanic is really neat once you get the hang of it. I was pretty unsure of the looping mechanic until I realized once you learn more in higher up levels you can use the new knowledge to redo the early levels faster. That's a really fantastic way to tie the theme to the mechanic in a meaningful way
. Unfortunately I'm not too good and I kept getting stuck in the same place unsure of how to progress so I gave up, but that didn't effect my enjoyment, just made me sad I don't get to see the top. Resetting was a bit frustrating after a little while, I don't really know how that could be solved though. perhaps checkpoints but I worry that would interfere with the main loop mechanic.
All in all this game was a blast, fun but a bit too challenging for me. I think this is perfect for a speedrunner audience so you nailed it. Great work, thanks for making this :D
