So far what I've seen is amazing, its really grabbed me, but I kinda feel like I need a guide or walkthrough to make sure I see everything, and the lack of a gallery doesn't really help either.
Just that reading some comments here talking about "oh the scene on day x" and I'm thinking "i don't remember seeing anything that could have led to that", I feel like I'm missing so much and have no way of knowing
It is a common question we are getting as the game actually is starting to get quite voluminous with content.
While a dev-internal wiki is currently getting worked on, it's not going to be released to the public... at least not yet. However, we are currently working on an in-game feature to show you progress.
