Tip: Take advantage of easy to install Patches in your hack. The No More Sprite Tile Limits or SA-1 patches should be considered if you're encountering glitches where Mario and/or sprites are turning invisible.
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 user-friendliness. Projectile has been modified, so it works for both the Pompon Flower and Yurarin Boo sprites. Added screenshot, tags and SA-1 support.
