The idea is really cool! Figuring out the puzzles were a lot of fun and honestly I can see this easily becoming a full little puzzle game
One thing I noticed for sure though is that the first 2 levels were a lot harder than the 3rd so it felt like the levels weren't progressing in difficulty. That'd be my main gripe everything else is great from the music to the artstyle!
I did only manage to complete 7 levels as I got stuck on the 8th but overall great submission!
