Great music! Adorable graphics. I really like the style overall. The mood is fantastic.
Gameplay: Interesting idea. Gives some nice mechanics. It's also relatively varied.
Sadly, there've been some small things that bothered me: - It took me a while to get the correct entrance to the third level (where you have to go down). I was not paying attention to the clouds, and they are gone once you collected enough souls. - Travelling to the right side of the screen, I started to glitch around. This happened in other locations too. - Fourth level I got stuck again, as the right rock did fall over, so I was unable to reach it from the right side. I noticed you can reset them by pressing R, and I finally made it after a few attempts. Don't know if this is intentional. - Sometimes the fox gets stuck, which is often fixed by crawling backward a bit and retrying.
These are all small things. Unfortunately, they added up and caused enough frustration to break the otherwise wonderful experience.
All in all, it's still an extraordinary game. I'm glad I found it and was able to play it.
