Demo 4 is here! Let's go over what's new: 

1. The Insane World (world 4) levels are in! These include the hippie themed Forever Flowery Fields (and corresponding secret level, with wind), Lightning Bolt Lake, and a boss fight against Larry McPeel.

2. Level design adjustments have been made, notably to Super Freaks Stadium, Vs. Milk Man, Barrel Canyon Cliffs, and Shipwreck Poopdeck. The difficulty curve should be a bit smoother now.

3. Wall jumping is a bit easier to do now, thanks to a slower wall slide and much higher grace period for jumping off the wall.

4. Dying enough times at a checkpoint will spawn a Yorb Star, which if collected will grant you 10 hearts. If you're having a really difficult time with a level section, this should help. In the future I will add an option to disable this.
