First thing I wanna say is that I love the loading screens/transition screen art. Really nails that 90s CGI aesthetic and made me feel nostalgic despite this being my first time playing this game. The graphics, animations, UI, etc... all of the visuals are really clean and well-done. It looks and feels like classic Diablo, which is a treat for me, as Diablo 1 remains one of my favourite games of all time. The music is also really reminiscent of Diablo 1 without being too samey, so I'd say it's safe to say you've really nailed the Diablo feel.
The UI is nice and simple, not at all overwhelming, very easy to read and understand even without in-your-face tutorials. I'm still playing through, but so far here are a couple nitpicks I've had:
- When I move between floors, sometimes I'll click to move on from the loading screen and will accidentally click on the entrance to the previous floor, and the character will go straight back down to the previous floor.
- Minimap opacity option would be nice.
If I run into anything else I'll edit this post. The game's genuinely really fun, great work!
