Hey.
I have plans to implement a soft cap on the number of charges and cooldown reduction. It may already be added in version 0.3, but we'll see how much time I have left after polishing everything else I have planned.
If characters became "too big" for enemy, or enemy is much bigger everyone just disappear from the field screen, or are visible in parts.
I have plans to add more props to the battle screen and adjust the view so you can see more of the characters present, but that will come in version 0.4.
I really miss having a “delete item” button or items that can expand inventory. Just one merchant is not enough to clear this mess in inventory (To tell the truth, she doesn't sell anything worthwhile at all.)
There are 2 merchants right now. I will think about adding a way to trash items for 0.3 then.
