This is a creative art and music studio, not a traditional game. It's a Mario-themed digital toybox for the SNES where you use the mouse-like controller to draw, compose, and play mini-games. It's absolutely worth experiencing for its unique, playful charm and historical significance.
The feel is completely chill and experimental, requiring no reflexes at all. The big surprise is the full music composer and the infamous fly-swatting mini-game. It's a quirky, foundational piece of creative software. Give it a spin.
