is the final boss the guys fake wife and kid? or am i missing something

Somewhere in the game is a ligthsaber. You can find it and equip it to Nick. However to unlock it's full power, you need to find the batteries that go to it. Anyone who finds it will be put into the game to give people hints on where to find the Lightsaber. To win, place a screenshot of Lani having the light saber equipped and his status screen. (If the members of Team Four Star find it first, they will not be eligible to win)...

So I've beat the game already twice. But I feel like im missing some stuff in game. I still have ??????? mobs missing ive been flying everywhere looking for locations i missed but nothing. the only thing i havn't figured out is the clock tower and the missing cat mission in east cave. and locked door at the 2nd quest where you get the row boat. Or am i just done?...

Im at the end game, got the airship, all characters, all casino gear, and ive searched nearly everywhere, but i cannot for the life of me find the mystery key to get into the final dungeon. Help?

So for one of the later characters, you need to use casino coins to unlock them, instead of TFS points. How do you get those coins? Do you buy them in the 3rd town with TFS points somewhere? Thanks, and great job again on the release Tsurugikage!
