Having the game burn away as a result of you taking too much time is such a cool idea and really compliments the themes you're going for. Everything here is insanely solid and the art concepts are gorgeous as well. The only thing I'm a bit concerned about is how the Page Burning Timer (tm) would work in game based on how much it wittles away at the screen a time but that's something to do playtesting with more than anything. Additionally, your production plan seems rather barren and too simplified to follow but that may be a personal thing. Super excited to see how this comes to fruition!
