Wowsers, congrats on your first game! You've come up with a good premise and I like how you've pulled out different mechanics and consequences from it.
The other comments have given great pointers on puzzle design, I wanted to add a note on the control aspect.
I personally feel the player movement is a bit too floaty for a fast paced puzzler, since I spent equal parts solving the puzzle and wrestling my player in the direction I wanted to go.
Please do consider exploring the mechanics further in a post jam update, I'd love to see where you take it!
