The bug you mentioned has been fixed, thanks for pointing it out. I forgot to put a flag in the event code that requires you to do the story mission to meet Katelyn before you can do the Cerel scene.
I can definitely add something to show what time of day it is, just changing the lighting isn't making it easy to know what time it is.
I want to do a gallery and eventually will for the scenes that are one time only, but most scenes down the line will be repeatable and adding a gallery is a lot of coding that would take time away from progressing the story and character relationships, which need to be at a certain point as soon as possible so players have choices on what to do, where to go and who to see, etc.
