Thanks for trying it out!
> The menus are frustrating to navigate. Why is there a custom mouse cursor if nothing can be clicked?
The mouse issue will be fixed somewhere in the future.
> The boss music against Anna felt like it was blowing out my eardrums. I have my OS volume set to much lower than it was playing.
Thank you for the feedback. I will try to experiment with setting a proper volume for the music, so it won't kill your ears.
> So, the way I got into the game was selecting constellations and then the first option, but the first time I tried it had a phantom dialogue cutscene playing over the game. Like I was moving around and enemies were firing at me but the text box, Lily, and the vampire were blocking most of the view.
Also, I have no idea if constellations were the right way to play lmao. I just selected stuff and shit happened.
So, the dialogue can be hidden / shown by pressing 'D'. If you got into the main gameloop via pressing a bunch of 'enters' then it worked as intended. Constellations are just highlighted by default if one wants to customise the spells. These three boxes, achievements, profile name, constellations, are navigated by using UP/DOWN arrows and by pressing 'E'. Pressing 'enter' results in the same behaviour as clicking on the LOAD button, i.e. it goes to the difficulty selection.
