This game has so much polish to it. The music fits really well with the aesthetics of the game. Few small notes, aside from the cooldown because you already know that. It would be great if there was a checkpoint between the first and second set of spikes. It took awhile for me to figure out the second puzzle and having to go back through the first set of spikes again got very repetitive. I love the art for the platforms, but I think it could be improved in the areas where there are more than just one set of bones. Instead of having let's say 6 of the skull sprites in a row, it'd be cool to see them mixed up a bit. Another very small note is that for the death count in the top right, it looks almost like a negative value so I felt like I died a negative amount of times lol. I don't have that much else to say about it because it is a really beautiful game and very fun to play. Great job.
