Interesting story, the writing is decent. I suspect since this was done solo, most of the development time went to the writing.
I would have like to see a bit nicer UI, with more sound effects. One particular suggestion I would like to point out is that the tome font could have been a more legible one. I know you were going for the aesthetic of an old book and old looking font, but the font being harder to read is directly interfering with the game mechanics of requiring you to read a lot. If aesthetics is still important, I would suggest you give an accessibility option to switch between the default one to a more legible one.
