Pretty cool game! I like the puzzles and how tricky and mind-bending they can get at times! That said, I do feel like there is a bit of a difficulty curve problem, with the first levels being easy and linear, then suddenly a really hard level, then easy and linear, then super hard. Maybe move around the levels a bit and add some more 'learning mechanics' levels. Also the movement can be a bit frustrating: feels like you're moving through water, or even tar, with how slow you go. Also it's a bummer that it didn't save my progress.
