Thanks for the video! I just received my pledge and haven't played it yet. Few things I got from it are: Automa is nice and straightforward which isn't unusual for byos. I got the upgraded metal tiles but looking at the amount of sliding I think I might be better of using the cardboard ones to reduce scratches on the board.
I didn't get the metal tiles, so I'm not sure how bad the scratching might be. I was figuring they were fairly smooth on the back, but I don't have any to feel. Let me know how it is if you choose to use them. Thank you for watching.
