Use the mouse to aim and look to throw the masterball. Catch MissingNo to win! Also, there's only one masterball, so you get one chance, I wasn't kidding about this being extreme, good luck. Also, comment on what color the grass is in your game, it should be different for everyone. My grass is purple with a tint of blue.
In this project, I tried a bunch of concepts I've wanted to try for a while, tell me what you think.
