Thanks for your feedback, glad you like the game!
1. I'm working on an official walkthrough at the moment, yes.
2. this is one of my major concerns. While working on the game, I still change some basic stuff that would lead to bugs, when transferring an old save to the new version. But the next update will include some sort of "skip" option to a specific point in the game so that you don't have to replay everything again. for fast progress you can also always use the in-game cheat engine in Benbo's Hut.
