It's fun! I thought all the puzzles were clever. It also has really nice music.
The ice effect and its fading on death is a very nice touch.
I had a bug where I slid off on Dual Purpose and then left the room and it kept making an ice sliding sound until I died.
I won in ~26 minutes and spent the most time & deaths on Dual Purpose. I didnt find any of the writing interesting, so I'm glad it wasn't mandatory to advance.
It would be more diegetic if rooms that require you to hit icicles to advance have a frozen door (to imply it melts to open) and monkey statue rooms had a mechanical door, instead of just a barricaded door that opens.
