Super cool idea and nice game overall! I agree with the points in the other comments - faced the same issues myself - so I'll add some other comments, which aren't gameplay related.
I think it'd be nice if you added a soundtrack, SFX and a narrative to this. It doesn't have to be good - it could be any boilerplate background music + some free SFX off itch. And a simple narrative - you're an archaeologist stuck in some ancient temple and need to get out. Anything works, because it'll greatly increase immersion and the overall player experience.
Here on itch.io and the amateur indie scene we focus so much on mechanics that we forget what makes games games - the intersection of A/V, storytelling, and interaction. Without A/V and storytelling, games are toys for adults to fiddle with, not games. That's my 2c at least. That being said, I did really enjoy the puzzles and the mechanics. The core components of a great experience are here.
Great job and thanks for a fun 20 minutes. Kinda inspired me to try some puzzle platformers now haha.
