this is my l4good island demo. this will be the first world in super L4good world. i will be making more demo to keep you updated on this hack but for now theres is onlt one world. everything should be fixed now. enjoy this hack and have fun.
New version: fixed the exit placement in "the water path" level, where Mario instantly dies.
