What makes the game especially hilarious, though, is that the entire world is built around the same jelly effect. If Mario jumps into a green pipe, it will bend and twist in bizarre ways. If you stand still and let a goomba walk into you, Mario will be shot backward with explosive force. Things get especially strange in stage 1-2, where bricks will break apart into dozens of tiny pieces if you so much as graze them. The music is similarly unnerving: while the tunes and sound effects are all familiar, they bend and contort based on how Mario is moving on-screen. It sounds wrong.
The Super Mario games have always been strange, but Jelly Mario shows that things can actually get even weirder. I wonder what Shigeru Miyamoto would think. You can check it out in your browser right here.
