I'm potentially thinking about spend more time working on this project.
I'm maybe going to add:
-(DONE) a camera that zooms out with more jump height (so the ground never goes out of view)
-smooth camera (if it ends up feeling better)
-(DONE) animation on the walking of the lich
-(DONE) change the balance by starting off with lower jump height (maybe 1-2 blocks at the start) and then progressing to the higher jumps/faster movement.
