Is There an "Unlock All Levels" Cheat for Drawn to Life?

No. Drawn to Life (DS/Wii/PC) has no built-in cheat code to unlock every level. Progression is tied to completing stages and drawing custom heroes/objects—core to the game's design.

External tools (Action Replay, save editors) exist but risk corrupting your save file. The intended experience is to play through creatively; each drawn element unlocks new areas organically.
