Thanks for the feedback, glad you liked it!
Yeah, I had massive problems with visual clarity during the boss fight. I wanted to go hard with the visual distortion and collapsing game world thing, but that made the game really difficult to navigate. That's then main reason you can not die at the boss fight (and if you didn't go below 0 HP, I applaud you, because that isn't easy). It's also the main reason why I didn't use enemy projectiles during normal gameplay; some visual modes just make it impossible to dodge those.
As for the dialogue, I hoped to catch the line between sincere and over the top. Like, it's the story of a generic fantasy game failing and breaking down; it's a bit sad and dramatic, but ultimately quite silly. I'm not much of a writer, so maybe the dialogue didn't convey that successfully and just reads as self important. Definitely an area which I can improve.
