Hi, and welcome to Level Editor 2.1! In the 2.1 verion, there is an undo botton, a redo botton, a save level featurre, and say you get stuck on a level, you can press the edit botton! When you hit play you are the purple dot at the bottom left. Try to get to the yellow. To make platforms, use the black tool, by cliking the box up in the top left corner. To make the goal, use yellow. Want a boost? use blue. Boring background? use grey, witch can't be touched. Want more chalange? Use red, witch starts you back. White is eraser. And thats all for the modes of pen. This verion is way better! Special Thanks to tacoswami for the help! Have fun and remember to love-it, fave it, and comment!
