Thank you! :)
A gallery that allows the player to review memories they've seen and easily replay some key scenes from it is high on my to-do list as I think that's an essential part of making the experience smoother. It should be coming in one of the next updates!
I'll keep in mind how to give the player some knowledge of what they can and can't do. While I believe that exploring the game and its options to find everything is part of the fun, I understand and share that sentiment as well! I promise I'll do my best to judge what'll be the best course of action in that regard. :) I do have some possible ideas on how to approach it.
