I understood precisely none of it. I felt precisely all of it. I suppose this is the feeling of traveling to Evernost.
On a serious note, a "game" like this takes serious attention to detail. Everything feels so intentional, and with the story being so abstract, every little moment you create with adding music, or exiting the game with a CSS warning and all the art... It all feels so cohesive even though I'd need to spend a year playing it to understand it all.
As far as the improvements, yeah. Good job.
