Editors were about the best we had before Drawn To Life hit the scene. That game's formula for creating art that was incorporated into the main game solved one of the biggest issues with editors. It is easy to give someone a sandbox and let them build a level, but harder to make a level anyone wants to play. We have all gained a great deal of respect for level designers through the process of fiddling with levels in an editor. The brilliance of a hybrid like Drawn To Life: SpongeBob SquarePants Edition is in leaving level design to the experts while still allowing players to customize most everything else not bolted down. There shouldn't be any positive impact on playability from drawing your own enemies, characters, power-ups, and incidental items. Nothing fundamental has changed about the level or the game's physics, but players immediately have a greater investment in the game and are willing to overlook a lot that normally would not pass muster.
The music and sound effects in Drawn To Life: SpongeBob SquarePants Edition aren't customizable in the same way as the visuals, but there is the option to replay music through a boom-box in your "base of operations." Of course, you get to draw your own house and boom-box... There is a lot of theme music within the game, changing at every stage and during special sections. There are some cut-scenes that tell the story of 'Bob and his friends working through a bad time in Bikini Bottom, but the majority of the action unfolds at street level with non-stop platforming. The characters and items you draw mesh nicely into the background thanks to an art style in the game that doesn't look overproduced or polished.
