1. The Vertical Slice has been done for some time, and right now we are over two months into production. We aren't planning on releasing a playable demo of the Vertical Slice or releasing a video of the VS. I know you are dying to see the game in action. Hopefully soon
2 - 6. You will get some more info on all of this soon. I apologize that it's taking us so long. The badges, memorial stone, item, NPC, adventuring party, and portraits will be connected with the fulfillment site. I've seen it! It's looking great.
7. Mac version is going good, and we are working on the Linux version. Unity makes it easy with porting it over, which has made my life easier.
8. Justin has been pretty busy with composing new music for the game, and has been working with real live musicians (and choir) recently. I was present at a rehearsal session last week, and it's an awesome experience to hear the music played live.
9 - 10. The novella and Tim's cooking book is going to be released with the game. I don't want to step on their toes - but everything is coming along well.
Cheers!
