Good job on this. This was a fun little game. It wasn't exactly clear that I had to get to the top of the level but also, there wasn't anywhere else to go. I did try to double jump up the wall but that was slightly out of reach, so that was good level design since it was then pretty clear you wanted the player to use the platforms.
Love the modifiers to add speed and the double jump. The pits would have been nicer if they had sides to them to add depth. There's also a few light gaps, likely due to meshes not being snapped to a common coordinate.
