I found out that the demo of happy wheels is now V1.52! that means everything in the level editor on the full version is in the demo! and you can now test your level! there's 3 new featured levels but this doesn't effect the characters, you can only play 3 characters still! this happened a few days ago! I thought it was a bug at first, and its weird, he added the NPC's into the editor! you can not place a featured level with a forced feature character in the demo!
