I'm writing because I'm stuck, but before I figure out how to encode that, thank you for this game. What makes classics classic in any genre is they use the medium to tell a story in a way that wouldn't be possible without that specific format, and that's what makes your point and click feel old school more than the pixelated aesthetic. This is a great combination of timing, wordplay, and visual detail, and the puzzles feel 'real' -- enough of the puzzles tell a story that nothing feels like it's randomly been dropped in the wrong room just to add to the gameplay time.
Going to try to give hopefully non-spoilery clues to where I'm stuck.
- I have red, blue, and grey keys, but not yellow. I've used two keys so far.
- The guardian is still guarding, the stars are obscured, and nothing's solved with beast and bird. I can see the cosmos, and I've gotten zapped.
- I've found and correlated a few clues about the time, but aside from taking notes haven't found out their purpose.
If that's not enough to explain where I'm stuck I can answer more. As an aside, does gameplay require people to click on a fast traveler? I've spent way too long trying to get the timing of that to work.
