Thanks for your feedback! I hope to eventually find the time to expand the built-in cheats. It’d definitely make things easier for players who don’t want to replay the story multiple times just to unlock all the scenes. I can’t promise any specific timeline for that, though.
As for the extra content in the paid version, I totally get where you’re coming from. That said, the extra content isn’t canonical, and there’s not a ton of it, so you’re really not missing out on much.
