Ok i played through Episode One now.

I really enjoyed the gameplay but the story is what hooked me. It is pretty intervened and the fact that you are able to play with all sides is great. I want to know who Frederick is, why is he still alive and why is Seti so old, where is the Keeper and why is Marcellus still alive? If hes an crusader does he only use the king to get the crystals to kill the lost or what is his scheme? I hope to get many answers with the next episodes.

I also encountered the stat bug, but it did not bother me. Epoch with 500 Agility and maxed Att and Def just rocks.

I think it is very industirous that you implemented a new character system with each character and the whole Linguardia guide of course. The Quest helper function seems a bit redundant from time to time because the game is so linear.
The Tarot system seemed a bit random, i don't know if the chance to get a positive effect is 50/50, but i guessed it and so i did not use it except for sould rends. Maybe you should explain that in the tarot instructions.
