Hello, I just feel like releasing my first in-editor-configurable boss. Has pretty much most of the configurations that affect its gameplay: the health, the speed, and the projectiles. So, have fun with this bad boy!
Credit goes to PROX for the sprites, MmmMario for an inspiration of his SMBX-38A level and Thwomp Thrash, that comes along a Thwomp Boss. Lemme know if there are any issues.
