I get the feeling you're just getting started with this, but you've done a great job already! Thank you for building this!
I know you're looking for feedback, so here are some ideas:
The inventory space is six items wide, and seven items tall, so there is space for 6 x 7 = 42 inventory slots, but only 40 slots are enabled:
You could raise inventory limit from 40 to *42* and the user interface would still look nice!
Also, I'd move the Enchant button from where it is now, below the item list, to *above* the item list:
...because the item list is constantly changing as you pick up new items. That causes the Enchant button to jump around on the page when you're trying to upgrade. It's hard to click it when it won't stay still.
Also, we could use more armor enchant scrolls! There are six armor items, and only one weapon item, so ideally we'd find six armor enchant scrolls for every one weapon enchant scroll. My experience was closer to this:
Also, it looks like the auto-sell algorithm keeps Hero items in your inventory, and sells everything else. This caused problems for me in the early game, when it sold rare items that I wanted to upgrade in the future. I was very sad when the auto-sell algorithm got rid of them against my wishes.
It also caused issues for me in the late game, when unwanted Hero items completely filled up my inventory. This interferes with the Auto-hunting, because you're forced to teleport back to town, due to a full inventory, before you've had a chance to actually hunt anything.
I wanted THIS auto-sell algorithm:
1. For each item in the inventory, sell the item if there is a corresponding equipped item, and the *base value* of the inventory item is less than or equal to the base value of the equipped item.
2. For the remaining inventory items: keep the best item for each slot and sell everything else.
That way, the auto-sell algorithm would never sell an item with greater potential than your currently-equipped item, and it would clear out the useless Hero items when you're in the late game :) Which is exactly what I wanted!
Also, in the early game, the Auto-hunt algorithm controlled which location I was in: whereas, I wanted this to be user-controlled. I never wanted the Auto-hunt algorithm to teleport to a different location.
Sometimes you want to farm an easier location, so you can get more upgrade scrolls. Sometimes you want to farm a harder location for experience. It should be your choice what you'd like to do!
Anyway, I hope this helps :)
