I agree with that part. She deserved more(or the players deserved more of her?)About no Susan: Susan was mistreated this whole game, in a level that three things can be said.
And I get where you're coming from. Although I'm also a bit disappointed with the ending, I'm not blaming you or FFcreations. You guys made the best of a bad situation. And at least the game wasn't outright abandoned. The ending is... well, it is what it is. The game's complete, and that's what matters.
Who knows, maybe in the future, the game could get DLCs to resolve some of the issues. Let's just keep hope alive.
