The only thing is I'm starting to think this game will be to easy, even on Normal. (There's only an easy and Normal Difficulty options. )

The only thing that seems silly is the fullness meter. You can basically feed your Familiars in order to strengthen them, but you can only feed them so much, then you have to wait until Fullness goes down. It goes down so fast though it seems irrelevant for it to even be there.

There's some other details about it I'm currently iffy on, though that could get lengthy, and I'm not really sure enough at this stage to say for sure anyway.
