Level Desginer - how does it work?

[jeremypotter]

i built a level but,i can't play it. i'm wondering if you could help

Did you save the level? (click "special" in the bottom right corner of the level editor, then click "save" in bottom left corner, type in the name of the level and click "save")

Once you have saved the level you can play it by going to the main menu, click "Play Game", then click "Custom", your level should be there, click it to play.
