Wow you seem to have played it a lot since you unlocked lightning spellsl. Thanks for the commitment!
First off, the UI options (and the UI scaling for that matter) will be worked on next. The resolution settings are indeed just a factor for scaling the 3D viewport, hence the muddying when scaling to anything belo 1920x1080. I quickly put the settings part together some time ago and never went back to actually make it do what it actually should.
Balancing input is always appreciated. The dungeon size really seems too big and because of that the experience gain from killing monsters will probably need to be higher too. At least in the first level to get started.
Starting equipment is a more complex matter as i will need to figure out if there will be character creation paths that will determine your gear. If so, what else will it entail? Will it give you a starting skill? Just a skill tree? Or maybe i just put in a dialogue on arrival that will gift the player something. We will see..
That troll bug is actually bigger than you might think, because you didn't meet the troll! The shocking truth is, i attached the wrong data object to that miniboss... Great find!
Inventory bugs were not known, but anticipated (never build a tetris inventory, its hell!). Thank you for uncovering them too.
Thank again for the detailled feedback!
