Inventory glitchyness aside, its a cool game. But of course "polish" is what distinguishes things. Right now, it needs a lot of love in the ui and user experience department, but it seems that the base is there already.
My issues were:
Rogue is the mvp, dealing 50% of damage, meaning that he's singlehandedly better than a tank, a ranger and a healer combined. And before one says 'well they are contributing their own way', nope. I wish I could have 4 rogues as a team. It's either lifesteal is overpowered or the rest of the squad are funcionally useless.
Tank does not tank. I think there should be some damage reduction passive on him. Because all else equal, he has twice the defence of a rogue and dies instantly while the rogue goes on to solo past 13 floor.
You expect the character order to protect the 4-th slot, but its in a circle anticlockwise, meaning that my healer on 4th slot in closer to the enemy than my rogue on 2 slot .
Healer revive has low priority, it will keep draining mana on a 40mp 6% heal instead of a 40mp 40% revive. This is just frustrating.
Same thing with tank. He pops invulnerable at the start of the floor before getting into the fight and then spams taunt till dead, which, with no invulnerable , happens rather quickly. Rest in peace brother.
I spent 15k on a chest to get a lvl9 item that I didn't need to sell it for 35g. There is no reason chest need to be this expensive being how pointless they are.
The skill tree could autosave, I don't see why there needs to be a button.
There needs to be a shortcut to floor 5 if I defeat floor 10. Just saying.
In gear tab it would help to see the gear's stats if I hover over it. Just saying.
This is just from the top of my head. There is potential, but these issues are layering on one another.
