Okay. I've basically finished the mod already anyway, and just need to test it. The only glitch so far would be when you're playing as Curly, and either the fog background doesn't work, or the fog background works but the game only scrolls at a speed of 1 pixel per second. Putting <KEY before the <MNA command at the scrips portions (ex. <KEY<MNA<CMU0030<FAI0000) will randomly work for some odd reason.
Anyway, this mod is yet another sequel to Cave Story's third ending. Somehow you're back in the first cave without [much] memory left above Mimiga Village, which is getting serious reconstructing, but for some reason Toroko and King are still alive, although the Graveyard clearly has graves for King and Toroko. After a wild goos chase with 3 clues, You end up in the shack again, but Balrog[?!] takes you to the doctor where he tells you to get Sue from the Egg Corridor (of all places) an you're suddenly there. But something's wrong and the Egg Corridor is in seperate time zones! When you finally get sue and bring her to the doctor, you and Sue dissapear, and you appear falling TOWARD THE MOON'S SURFACE!!!
Well, that's all for now. I will most likely make a showcase thread with demo v0.3 sometime later today.
EDIT: oh, yea, the screenshots will came a bit later as well.
Well, (sorry about the double-post) here they are. (Honestly, I don't know quite how to do that so Itook pictures instead.
