Some small but significant adjustments that should improve playability.
- Changed the hitbox on the running animation so that it should be easier to jump off ledges without falling (not coyote time though)
- Middle (white) worm on the boss of stage 2 no longer shoots acid at random! It's now in a predictable pattern. Also changed the acid color to stand out better against the background.
- Small fix on the background of stage 1
