Wow, a six-paragraph review? Thanks for taking the time to write out something that long! As to your questions:
1. You can post it here in the comments for sure, if you want to. As for advertising the game, honestly there isn't a great "marketing hub" for this kind of thing, but just spread the word if you can! I appreciate it :)
2. All saves are compatible between versions, and the game will automatically detect and transfer them over for you. You don't need to do a thing - just download the update and play! :)
Hope that answers your questions!
