* I'm sure this is in progress, but some main menu visual cleanup would really help it 'feel' nicer to start playing. Just rounding out button edges, making the background fullscreen, etc.
* Music is properly thematic though and cool!
* I like the style of the character and the world.
* The HUD is a bit overwhelming. It's okay for me since I'm an MMO player, but you could hide some elements like chat until they're needed.
* I felt a bit soft-locked at first, but figured it out. It said 'press next', but my cursor disappeared. I had to hit the windows key and find my mouse to finally click on it.
* The spells should have a description when you mouseover.
* I'd recommend adding a slight bit of lag when turning using A/D. It feels stiff.
* Tutorial says, "Hit the dummy", but I don't see a dummy.
* The 'Use Portal' and 'Portal Is Ready' area is so hard to read. Definitely improve the key things the player experiences quickly.
* The dungeons seem cool, but I don't now anything about them or what I'm doing. You need a 'Call To Action' - it can't be, "Get to dungeoning!" - it's 'Why am I going to dungeons? What's the loop of the game?'. Right now, that isn't clear.
* I entered into a lava-esque dungeon, nothing really happened, and I wasn't sure what I was supposed to do.
