Brutal Mario World USA

Brutal Mario World (also known as Super Kitiku World among other names like King Brute Mario, Devil King Mario etc.) is a Japanese Super Mario World hack under production by Carol. Although the game is unfinished, it quickly grew popular due to groundbreaking features such as a Samurai Kirby-type mini-game, all-new boss battles (mostly against cameo appearances from other video games), switches that dramatically change levels, and more, giving the game a fresh new experience.
