Firstly two things:
- Ash falls funnily. Whenever I went higher, the upper edge of falling ash couldn't keep up.
- I slid off of platforms, there was no traction. And trying to walk to match the platform speed was kinda hard due to how fast they were moving. And it was hard to judge where exactly the platform's path ended so trying to jump onto another moving platform didn't work out for me. This or I am just bad at platformers.
- The place just after the first ghost encounter - I got stuck beneath the first steps - I couldn't get out of there. You mentioned in your known bugs that edges of blocks are buggy, so perhaps you should block that place off with blocks so that no one can fall in there.
I can't comment on the story since I wan't able to get past the first moving platforms.
I liked the sprite jump animation, where it puts its hands/paws downwards whenever falling. It was a nice little touch.
