Hamerski 3D Platformer Tutorial

My three proposed modifications to the game are likely going to be new levels that are coherent with the existing game, but increase in difficulty as you move through the game. I like the idea of excluding enemies, but making it a significant parkour challenge to complete a level with keys and pickups.

I would also like to make modifications to the level select and main menu screens, as well as giving the game a new, unique name.
