*NOTICE* Since BoltBait is such a genius, I can't understand his coding, and therefore can't fix the bug where Tails get's stuck in the ground on the boss stage. When you get to this part in the game, simply go inside and drag Tails out of the platform. Thank you for understanding. Now Tails is stuck in Mario and Luigi's world, and he has to save Peach! Use the left/right arrows to run and the up arrow or space to jump. Make it to the green arrow to advance from screen to screen. Avoid lava. Enter pipes. Avoid enemies if you can or jump on enemy's heads to defeat them. Your final score is displayed at the end. Don't worry about losing lives, you have unlimited number of lives!
All the coding was done by BoltBait, the only thing I changed were Luigi sprites to Tails sprites. 1.1 UPDATE: Added a very bad running animation so that it didn't glitch from run to jump when you ran. 1.2 UPDATE: I think I fixed some bugs that made you stuck and slide along the ground.
