Decently polished. Nice art style. It seems like a fun game but I got stuck at the first checkpoint and couldn't figure out how to continue from there. Maybe I'm dumb ? It seem like this concept has a lot of potential.
Yeah, unfortunately that puzzle isn't great and seems to stump a lot of people; the key insight is that your soul has higher initial speed if you are already moving prior to releasing it, but it's pretty subtle and not at all intuitive.
