1) Go to the sprite named "Level ART" 2) Delete all the previous placed level art costumes 3) Design as many new levels as you want. 4) Go to the sprite named "Level HITBOX" 5) Delete all the previous place level hitbox costumes 6) Go to "Level ART" and drag EACH costume IN ORDER from the ART sprite to the HITBOX sprite
Well as you can see, this was a huge failure. Have fun, and for heavens sake, fix these bugs!
