I've ended the game at lvl 35 with a white mage and a lot of wisdom at hard.
BTW that was fun, but here is some feedback :
*Pets are _way_ too strong. I guess it's my wisdom that multiplied their magic attack.
*My heal spell gave me all my hp in one cast every time in the game. So there was no point to upgrade with skills. It was costing more mana for the same effect !
*The gold balance is weird. Until the end, all gold gained in battle is just enought to pay the inn or so. All the good and all the stuff we equip come solely from chests.
*The wizard cape is useless. By the time I found it in a chest, I had 27'000 in magic attack. So the +500 is worthless. Why not giving 3 point of wisdom instead ?
However this is a pretty good game.
