A second update from me (authorized by Blind Devil) to add an option to have the sprite die immediately (just like any normal Super Mario World sprite) instead of falling to the ground and then dying after a couple of seconds. Check the ASM file for details.
Fixed squished state sprite interaction with the player, as it was possible to capespin, kill it with fireballs/kicked sprites or eat with Yoshi during this state. Defines for tilemaps were added for more user-friendliness. Removed unnecessary code. Added screenshot, tags and SA-1 support.
