This a repost from my school account. The description reads as follows: An Extra-Evil Goomba has invaded the Mushroom Kingdom! Mario needs to stop it before it takes over! Use the left and right arrows to make Mario run around, and use the up arrow to make Mario jump! Jump on the Goomba 3 times to defeat it and save the Mushroom Kingdom!
Notes: If you jump onto the Goomba and get a Game Over anyway, just reset, it's a very minor bug with the collision mask. I haven't found any glitches other than that. None that I haven't fixed, anyways. Heh. Credits: Myself, back about a month ago. Mario and Goomba edited from Super Mario Bros. by Nintendo. "MARIO" Title graphics and "Game Over" Graphics from Paper Mario by Nintendo and Intelligent Systems. Audio from Nintendo and Intelligent Systems. The rest is made by me!
