Adventure Time (Working Title) block collision test 1

This video shows off a specific aspect of the horizontal collision detection. When a collision happens, movement is stopped, but forward momentum is momentarily retained and decremented each frame. This way, if you touch the corner of a block while jumping, you'll continue moving forward after you clear the block vertically, at a rate relative to the length of time it took to clear. This helps prevent frustration when you, either from a small mistake in timing or from hitbox ambiguity, accidentally collide with a block when you are trying to jump over it.
Keeping with the theme of the previous video, the music is "Mandala in the Clouds" by Bear McCreary, from the BSG S3 soundtrack.
