You're talking about only having a single character, right?

From what I can tell, the game's story is based around two main characters, and the combat is balanced around having a party of four (with increasing difficulty as the party size shrinks). It would be quite a bit of work to rebalance every combat encounter in the game. Plus some puzzles are based around having two people.
