The puzzles were nice and I liked the little cute ending. I think I missed out that the buttons were toggle in the stage that teaches it by doing the puzzle correctly the first time. It made me think the buttons were one time use and would be wasted if the pillar was frozen; which threw me off on the last level.

Thank you for the feedback, I really appreciate it! :)
Yeah, I totally agree with the assessment here, I think the number one flaw in the final puzzle is that I didn't properly convey the toggle nature of the purple buttons versus the one-time-use nature of the orange buttons as well as I had hoped to.
I'm glad you liked the ending!
