don't forget that the food mace can help alot. not sure by exp point going to upgrade, it is by random choice so if your max food points is less than the mage use the food mace. ;P
this game is easy and fun. and i enjoyed the 15 hours i just killed everything is upgrade plus tip: the levels ice and drak cave best to use the ice wand a bit to slow them down and kill them with the punch, meteor, or undead mace i recomment the undead wand in the 2nd last level can kill instantly with one hit if ur lucky enough.
