I finally got all the endings (on Android the color scheme is easier to read than on desktop for some reason). I utterly love all the characters. I also enjoyed the art collection PDF.
MINOR SPOILER WARNING:
When I first saw Cici's color scheme I thought it might be a hint that she is trans. I was a little disappointed that that information wasn't revealed in any of the endings or in the art collection. Maybe it doesn't actually make sense to feel dissapointed, because the game doesn't actually say Cici's trans so I shouldn't have expected her to be. My response is probably irrational.
Even so I really enjoyed Bea's reveal.
