I got the god-like feeling after I started min/maxing my items. Using the gem finder too much and saving before getting good rewards quickly throws the game out of balance.
The problem is it goes too far to the other side (the game is too difficult) if you don't do at least some of that. I feel like the developers left too much of the balance to me the player.
It might have worked better with less emphasis on leveling and more on action/adventure (like shadow of the colossus).
