Played 0.16 hotfix.
Didn't finish the game yet, but I got to the golden goblin floor. Here are some thing I found.
Tried playing as a melee character again and I got rekt on the first floor. Ran out of poitions. Next character I decided to play as a mage and this is how my inventory looked like near the end of my playthrough.
This might be me just being bad, but I really think melee should be buffed. Ranged weapons allow you to get out of the way and you can clear entire levels without taking any damage. Can't really do that with melee. Giving to all melee weapons life leech or giving them regeneration weapon art might be a solution.
That said, playing as a mage was really fun. Your attacks never miss, and lightning disc is really fun. Sadly other spells are not that useful. Fire trap takes too long to triger, fireball is too weak / very little area of effect, ice spikes are not that strong and they don't pass through enemies.
I had mana leach on most of my items so I could spam the disc pretty much all the time, since it was much better than any other spells.
Next something minor. Visibility behind walls is slightly iffy. You can see boss / elite enemy effects in rooms you didn't even visit yet and the rooms them selves are visible without visiting them too. Seeing an empty room fill with enemies when you open the door doesn't look very good. Exanima does that nicely. your character can also get obscured by walls sometimes.
This is also a minor thing, but skill requirements for books after reaching certain level shows 9999. I'm sure this means I reached max spell level, but displaying "Max level reached" would be better.
Now for the more serious stuff.
You can't put potions into potion slot by holding and draging the potion from your inventory into a full slot. Potions don't swap, while they do when you click, move and click the full slot.
You can duplicate items if you place two handed weapon into your main slot while having both of them full. Here I have ground full of duplicated wands I made with the two handed staff.
Lastly, saving is broken.
First, I tried to save, selected a slot and pressed esc instead of entering a save name. This put me back into game. When I pressed esc again, I got instantly thrown into the save screen and the prompt "do you want to overwrite the file?" was showing. Pressing the esc again put me back into the save screen, but all buttons (delete save and back) were missing. Esc put me back into game, pressing it again put me into the save screen with no buttons again. Saving the game made all the buttons come back.
After that, I actualy tried loading a game. That's when the weird stuff happened.
I quit to main menu and loaded the latest save (Golden goblin level). I loaded into what looked like the skeleton level, but I was stucked in some corner, unable to move.
Then I quit the game completely and loaded that save again. Waited for about five minutes and nothing was happening. The game didn't froze, because loading animations were playing, but nothing else was happening.
Alt+f4 fixed that. I tried loading slightly older save and I got loaded into the bone zone level. I had all my items, but the level was wrong.
Tried to load the same save again and the game loaded for minutes without anyhting happening.
Other than that I didn't really find anything else broken. New UI is nice and the graphics are getting better. NPCs are a good addition, although I would slow down the text scroll speed a bit and allowed players to scroll the box up / down when they click on it.
And one last suggestion. At the start of the game, you start with 3 potions, sword and a bow. Please add some kind of starter wand also. The game is getting better. Keep it up.
