Thanks for playing and the feedback!
I added camera collision in v1.3 that should help with the trees being in the way, but I agree, they are kind of annoying in some levels.
Ragarding the dash+jump combo, I didn't add the ability to jump because i wanted to make a jumpless puzzle/platformer (similar to captain toad). Sadly the puzzle part is kinda lacking because of the time limit of the jam. I would have liked to make much bigger and complex levels.
The dash away from the camera instead of youmu's direction is easier in my opinion, especially since she doesn't turn immediately but has a lerping effect on rotation.
Also, I would have loved to add music and sfx, but I ran out of time, much like the last jam. I'll try to manage my time better for the next one!
