You have done a great job outlining plans here! The scope seems perfect for the length of the jam, but I like that you also included some "stretch goals" ("Maybes") that might be possible if time allows.
I'm also really impressed with how succinct you kept each section, and how accessible these documents are to skim through and find the information you're looking for. Great work so far, and I'm really excited to see where you take this one! :)
