This patch gives the Cape (+ Bounce Blocks too) the ability to "combo" a sprite.
If a sprite is repeatedly struck with the Cape (or Bounce Blocks) before it hits the ground, it'll accrue score similarly to a stomp, thrown shell, or the Star ability.
The patch uses two bytes of RAM; one to keep track of which sprite is being combo'd, and one to track how many times it's been hit.
The ASM file contains defines allowing you to specify which two bytes of RAM are used, as well as whether or not the incrementing SFX is played.
I encountered a bug where the score combo doesn't reset even when a sprite lands (by juggling two sprites at once), but barely could get to replicate it. Otherwise everything works pretty much as intended.
