Nice work on this! Puzzles are really hard to make, and I felt the difficulty for your puzzles was just right. The addition of a tip button is also a really good thought (especially for a game jam entry)!
Given how polished the game already is a slightly better transition on death would have wrapped it all up really nicely. Also, the music was nice, but mostly absent during the actual play through, I would have liked to listen to it more.
The inclusion of a story to set it all up and explain new mechanics were great. I think you’ll end up doing very well in the jam!
