First time playing it, apart from some initial stuttering in the beginning (which was probably the shader compilation) the game generally ran fine without any performance trouble. The party member system is interesting and generally worked pretty well (even when I forgot to equip the druid and had to watch him punch goblins with his bare hands, which was ended up looking pretty cool), never felt like they were too powerful to take the gameplay away from me, though they were pretty fragile (mostly because I didn't outfit them properly, but also because they loved to stand still in the goblin alchemist AOE). The centipede weapon/shield you get from the Rat King is really clever, I haven't found any other unique weapon like that (due to the issue below) but things like that are really fun to find.
Got into an issue where if I make it to the Mines 2 waypoint, close the game, load the save, go from the town to Mines 2, kill a few stuff and then teleport back to town, the game crashes. Was able to reproduce on both Warrior and Witch. Goblin archers also sometimes got up to a wall near a doorway where they clipped through just enough for them to shoot me but not enough for me to shoot back at the current angle, and found a Rosewood Amulet with the effect of <null>.
At 1920x1080, the UI felt generally pretty small - and by that I mean mostly the buttons, like in the title screen, or the X that closes the windows, or the level up buttons.
Having gold automatically picked up was confusing at first, as I never found any my inital thought that the only source was to sell off equipment until I realized I had more than I started with, and then noticed what the yellow numbers are that sometimes pop up after a kill. I imagine the reason is because picking up stuff has it's own animation? I don't know if you had pickupable gold before and then decided against it, but it didn't seem like it dropped often enough for it to become an issue, but of course the proper way to evaluate that would be to test it. Still, I feel that a good feedback for getting some coins in either way could do a lot for this game.
My Warrior gameplay felt good, both using melee and bows had a decent upgrade path and variety, but the Witch felt lackluster in comparison, mostly because the only spell I've found was Fireball (same with Warrior) and was left using the same gear as the Warrior. I don't know if the whole class and magic in general is new, but as someone who likes to play magic classes in these kind of games having a shop that gives similar options (and maybe even equipment that benefits from Magic stat) dedicated for spellcasters would be really nice.
