I just read this whole thread, and this is a very pathetic display of attempted programming. Was the beginning and middle of the game so good that there's just tremendous pressure to make an ending so good that nobody can actually make it? I mean, honestly, how can it take more than one day to finish this game?
P.S. Please, no minigame. That will just delay this process (the release date was supposed to be like September 2008). Plus it's rare for an RPG to have a minigame at the very end; usually that's where you just put repeated super battles with big bosses in a very lengthy dungeon.
Also, make sure that after you beat the game, where a game would normally say like "You win" or whatever, it says "You've broken the curse of Chain Game 4."
