What went wrong with the Platformer (Patreon)

A few people asked here or there what exactly went wrong with the Platformer tutorial that I've had to remake recently. I've not really been able to give the full picture in short text explanations so I figured I'd make a video to discuss it, along with the original method, what you can do to fix it and how it compares to the new method.

Will release sometime next week after the new platformer tutorial releases.
