Love the atmosphere, game is pretty responsive. I did encounter a couple of bugs but fortunately nothing big. You can't quit from the death menu and that the resume button doesn't work if you press Esc. Agility does nothing, I leveled it up but neither my defense or armor changed. Save works for the first file but not the others, haven't tried loading. Also sometimes the save button also does nothing, I think it's linked to the other bug(when I try to save in the 2nd slot).
As for feedback, I feel like the doors south west/east are almost impossible to see, when you go near a door to the north your light makes the door shine brown which makes it stand out from the walls, but the doors south of you stay black and if you get too close simply become transparent. Also I personally think that there should be a visible experience bar somewhere and I don't see why you have the player click a key when the level is ready, could just load in directly I feel. Another thing is that I found a couple shrines but I have no idea what they do from the message given, I guess a temporary buff but I didn't see it anywhere.
For me inventory management is a mess, right click to drop makes juggling weapons in combat pretty much impossible and drinking potions in battle also very difficult. Dropping items is usually done when you're not in combat so there's no need to assign an important click to it, you can just drag and drop them to the floor. Another keybinding thing, I wish you could just use your mousewheel to switch spells instead of having the circle with Q.
I played 3 times, my first game I played a mage since I found a fireball book early, it went pretty well except for the bloodguard boss which took forever to kite with the bow since he was draining my mana and I couldn't fight him melee without dying super fast. I still killed him and reached the 3rd floor but got ambushed by a dozen skulls that shot fireballs at me and killed me.
My second game I tried a melee character, I found 3 rare monsters this time on the first floor(didn't see a single one in my first game) and man are they tough to kill and not really rewarding. I died on the 3rd one which was a vampire girl with her groupies since I was out of health potions after the other two magic skeletons. I don't feel like melee is really viable compared to ranged since you use your health potions really fast considering monsters usually come in packs.
My 3rd game I went mage/archer again, things went pretty well, didn't use many potions since it's easy to kite mobs and dodge ranged attacks with the bow early on. When I got to the upper hall(the place with the goblin statue) my bow was starting to suck big time but I luckily found a hunter bow there which outclasses pretty much all the other weapons in my opinion. Crossbows are pure trash, slow, no damage and impossible to kite with. I unlocked a lot of spells, fireball, fire trap, combustion, poison circle, but the one that I used pretty much from floor 2 to the end was purifying circle, that spell was just insanely good compared to the others since it's both AoE and single-target damage with the multiple projectiles, it's only weakness is that projectiles get lost if you cast in a small hallway. I did make it to the end in this game but the reason will probably be very anticlimactic, it was because I looted the two best pieces of equipment currently in the game, %lifesteal and %manasteal rings. You round up the values so my bow was giving me 1hp and 1 mana per hit allowing me to pretty much facetank everything from floor 3 to 5 and have infinite mana. It got a bit more dangerous for floor 6 and 7 since my armor and defense were really low but I had accumulated tons of potions which allowed me to survive them. The spitters in the breeding grounds were especially dangerous but I saw that if you're melee they hit less hard so I guess that's how they're balanced. I took a screenshot of my end stats/inventory if you're curious. I don't think I could have won without the rings, had some close calls even with them on since enemies love to swarm you. I did have fun though.
