Seems like a really fun concept! Running games are great for that adrenaline hit. I had a few issues and couldn't finish it, though.
I played until the second jump (when you have to go from the bridge to the ramp to exit the brickstone maze, after acquiring the jump). It may be because I have an extremely old controller, but I couldn't make the jump work while using it. I found the timing a bit weird and hard in the keyboard as well. If these additional power-ups could be mapped as a single button then the input would be easier.
Additionally, a pause menu would be great, since while I was puzzle fighting with the inputs then animation of the trees raising was stressing me out. The menu would also be a great spot to put the controls (both for the control and the keyboard) available.
And if possible, giving the option to move both with WASD and arrow keys is always great, but that's already my own personal preference, haha.
