Thank you for playing, and providing me with feedback, I'm glad you liked overall aspects of game.
Yes the UI is mess, I mostly focused on graphics and gameplay. You provided a very reasonable feedback on UI it'll help me fix a lot of stuff.
I am surprised people have trouble advancing dialog. I my mid when people would see a dialog box they would press space or enter, both advancing dialog. Anyway I'll tell players what button to press to advance.
As a solo dev a I have habit of working on different elements of game without finishing or at least getting them to some proper state.
