This is a really unique take on the theme, and it controls quite nicely :) I can't say I had a lot of fun with the game because I really just don't get on with puzzle platformers, but I think you achieved what you set out to do pretty well.
I have a couple of minor nitpicks - it was pretty easy to make the puzzles unsolvable. I think that's my biggest issue to be honest, there were so many times I had to just jump off the edge to restart the room because there was no way for me to recover. Also, while the music works well enough and I think fits the vibe you're going for, it does start to get a little bit repetitive after a while.
It's cool to see a leaderboard in a jam game, always makes them more replayable :D I didn't really see much opportunity for speedrun strats, it feels like playing for time is just "know the puzzle", and the ones I played seemed pretty straightforward to me.
Overall, it's a nice little game. A unique take on the theme that works really well, with no major "bugs" and only a couple of minor flaws in the design. It also looks great! Good job 😁
