The audio is soothing and satisfying! Combined with the doodling art gives a distinguished feel; I feel like I'm playing a game on some yellow notebook paper haha!
There's little aesthetic details paired with the well-formed puzzles to make solving them intentional. The dotted lines were a nice touch to clearly communicate button intensions, even for colorblind folks. The spikes had just a little extra color for a nice minimalist boast, and the several boxes representing the exit were easy to deduce in function.
It's a splendid game and I'm glad I played it :)
