boss rush (press any key or click to change costumes) -------------- you must defeat every boss and miniboss in a row, while also not using any badges or powerups (minibosses displayed in project) oh, and NO yoshi or nabbit allowed!!! online is optional but i'd recommend not using it since it's practically just free lives
notice: only possible after the final boss level is completed also, i completed the challenge myself so i can confirm it's possible (some bosses are easier than others though)
