wow, i could NOT finish it.
I liked it. I liked the theme the art and everything.
One thing that works against it is that its similar to celeste in difficulty, but it has fewer checkpoints and a time limit. Every time i got to the chase sequence I'd start getting flustered, and I couldn't just sit back for a minute to compose myself, I had to keep trying or I wasn't going to make it (I didn't)
Mechanically, I think the game is really good. Realizing I could chain dashes almost instantly to get across a room faster was a pretty cool moment. I think the one thing that needs work in that department is the wall jump. I can't tell if I'm doing it wrong or if it just doesn't give you any height. Its not super easy to use.
All that aside, I liked it enough to make more than one full 9 minute attempt. Well done.
