Godot platform 2D player movement

This is a 2D platformer with a focus on really merciful player movement (it's on Github as well if you just want to take a look at it)

Implemented almost all mercy features from Dave tech - Tips and Tricks for good platforming games:
- Anti gravity apex
- Early fall
- Jump buffering
- Speed apex
- Coyote time
- Clamp falling speed
- Catch missed jumps
- Bumped head correction
- Hold shift to stay on ledge

Input:
A or left arrow moves left
D or right arrow moves right
Space jumps
Shift when moving for safe movement
