currently, the pet skill "meditation" seems to produce a message in the turn by turn updates that reads "your pet recovers # hp to you and himself" as apposed to reading "mp"
Sorting options for the deck and purchasing in the card game would be amazingly helpful. Also, there are duplicate card types, (like fire arrow & flaming arrow: same effect) not sure if its intentional, but would be easy to check if the purchase list could be sorted.
The upgrade system for the arena is cool, it should be expanded. Upgradeable rings would be sweet. Maybe you would have to unlock them via collecting a certain (large) number in loot drops. Or something...
