The New Features:
Ability Bar
The Ability Bar is a simple addition. It shows how full your ability is, when you can use it, and how much time it has left. It goes away when the bar is full. Nice way to visually see when you can use the ability.
Quick Turn Animation
Quick Turning (space bar) now has a very fast animation AND a (awkward) sound to accompany it. Now it doesn't feel like you teleport.
On top of this, I decided to make some other tiny improvements. Play movement should feel MUCH smoother now!
