Step 1: Delete the "DELETE THIS" backdrop. Step 2: Add a costume to the "CHARACTER" sprite containing your character. Step 3: Fill out the information about your character on the "Info" backdrop. Step 4: Remix, so I can see your character and add it into the next BFFFW episode.
The reason I ddin't wanted to do a debut in BFFFW 11 it's ebcuase I wanted to recommend Mciro but with a better asset, and that Traffic Lighters are no more of a character to me, Micro's the onle one I use now, plus, my art and assets were bad back at those times.
