This is just a template for a platformer. All the key colors are included. You can modify a certain script to choose a color for "next level" instead of the right edge. The "backdrop" backdrop can be duplicated as a base for a level, as I assume that the ground will always be either black or red.
Please remember to give credit to me when using this template, either by remixing it directly (in which case credit is given automatically) or by putting the "Platformer" sprite into your backpack, (in which case you MUST give credit to me in this section of the description).
