The browser version was a bit laggy for me so I didn’t play that much but I enjoyed what was there. I think the concept is quite interesting, especially since you have to work with the timing of the jumps and so on…
The camera movement was a bit annoying with the jumps, I suggest to only change the camera y position if the player exceeds a certain y-threshold and on hitting the ground (to stop the camera from moving up and down when the player only jumps on the same platform).
At any rate, I think you did a good job!
