First up, fun game. I'm liking it so far (1st soft reset in). A few ideas for you to consider; some kind of upgradable packmule to increase bag space, consumables being exempt from the level system (level 1 potions do the same as 10, so why would they get sold off? etc), more distinct differences between the heroes preferably in the form of passive buffs (healer heals more, warrior does more melee damage...), maybe some kind of upgrade system that saves between soft resets (again, passive buffs/bonuses would be nice) all I have at the moment. It's a good game so far, keep updating!
 "Idle Sword"){kind=icon}
 "Drop."){kind=icon}
Thanks! All of that is coming this sunday in one form or another (no passive hero buffs though). Thanks for the support!
