I understand that multiplayer has almost no chance of happening. But if it WERE to happen, I think a way more players could be handled like this:
Player 1 would be Kel obviously, Player 2 would be Ena due to the I don't feel well video. Someone would have to replace Ena in the emails during multiplayer, maybe Ken or Max would be the main person doing emails?
If this game were to be 3 or 4 player however, player 3 and 4 could be Kerfur-o's that you have to build for a player to possess so they can join your game. This would be to prevent the game from being too easy at the beginning.
