The mechanics of the puzzles were pretty straight forward but they  the were also tricky and felt rewarding. The drawings told a story I wish I knew more of, really good job. The last puzzle took a long time, but it felt like a "aha I got it! moment" when I beat it. It took me some time to realize that you can push and interact with all things that are more saturated/brighter than the background, maybe that could be more clear for the player? (I did not know you could push the mirror until I accidently pushed it).

Really have no complaints. Solid mechanics, fun game, and it even has an interesting story tied into it! Good job!
