The map is pretty small for the first area so having the tiles respawn makes it easier to farm items/enemies/etc. The interaction button being swapped is a good idea though I'll try that out see if it feels better.
I haven't fooled around too much with the player hitbox, the enemies do take awhile to strike but if it's difficult I'll look into shrinking it if it's egregious, I haven't looked too heavily into it. I'll see about making allies stand out more too in battle as well as figuring out a way to let players know how much health they're at or if they need attention.
I see your point about revives, in the next content update I'll roll the idea around about splitting the item into a version that revives in battle, one after battle, or maybe just bringing all dead allies back once a battle is won at 1 HP not sure yet. Either way it was intended to be the game's way of telling you to work WITH them to fight till they get stronger but I can understand why that would be annoying to keep having them go down.
The village does have armor for all 4 classes as well as the ability to gather most of the resources required for the armor inside. So it could be farmed if none of the other rooms are giving the materials for the equipment players want.
The volume stuff is intentional but I'll probably adjust it to be more traditional next content update. Also there is a way to go back to the main menu it's in the save box under "exit" I'll rename it to title as I can see the confusion there.
