I like the diverse jump options and the fact I had to learn them. I got about 60% of the map discovered, the part after the waterfall was really hard (played with keyboard).
For webgl, you can disable the mouse cursor by locking it on some player interaction, I did it as well for my game: https://docs.unity3d.com/Manual/webgl-cursorfullscreen.html
Also, just as with my game, a sensitivity option would be very handy. The mouse look is very sensitive for me.
