How's this design doc?

I’m making a design doc for my game and wondering if I hit all of the necessary pointers, if there’s anything else that should be added, or if there’s anything that I got wrong. Any suggestions?

I think this doc looks well made but I really feel like you should just make the background darker. If not on the first slide atleast on the ones later

Make it darker for readability?

Definitely. Other than that it seems great!
