Still quite new to the game, but I Just wanted to say that the UI/UX elements are a definite standout. Really, really good stuff.
One minor piece of additional feedback in that domain: I accidentally hit z and turned off loot tooltips at the beginning of the game, and I went like 4 levels thinking there just weren’t drops yet. 
(I even missed a unique, in hindsight. Couldn’t figure out what the glowing beam was for.)
