This was a very mind-provoking game, I definitely enjoyed tackling all the puzzles. The art and colors of the game really blend together, and the music does give that feel of the inevitability that draws near as you progress.
The only issue I noticed is on the boulder puzzle if you move some around just right, which isn't hard to do, you can block off the exit and no longer progress.
I definitely did enjoy that light puzzle though, but all the puzzles themselves were finely made and executed.
Overall, this was a very enjoyable game even if it's short, I wish you the best on any future jams or projects.
