Hi there, really nice game, been playing to it since yesterday and I'm able to do "Impossible Missions" already.
Let me recommend some useful things I would appreciate as I've been playing and thought... "Hey, I just need that" xD
1.- "Sort" inventory: being able to sort by rarity, value, whatever...
2.- After completing a mission, when the amount of xp and chests appear, add a button to replay the same level again with the same formation. I lost lots of time to farm xp and items.
3.- You could add another kind of attacks like magical where you use the wisdom or intelligence attribute. However that would need more items also to provide a nice build for mages or healers.
4.- When leveling up stats, it would be nice to have +5 or even +10 option for each attribute. Too boring to level up 1 by 1.
The above recommendations are in addition to the supposed improved interface and whatever you should already be working on.
