Make character, you can only use the sprite titled "ROBLOX SPRITE" as your defender, because this is supposed to be Roblox themed. No op characters. If you want to scale your defender, use the [set size=(100)] block so its easier to tell how big your character is. Other than that have fun! :) Also if you want to, you can change some parts of the sprite when making an enemy. You can make your character stationary or able to move.
