Hi, treeform! I think there are some problems in your code:
Still unable to exit with escape key
When i comment render.setShaderAuto() with # it has no effect
Jumping is very slow and not real (some kind of character’s center jumping, not the legs)
There is a mouse cursor visible during the game
No limits to move camera up and down
It’s possible to see teapot cover under the player itself 
PS. IMHO ynjh_jo has made jump process better.
Good luck!
