This was fun! Learning the map and trying to figure out where the different butterflies were was neat, but the changing music and lighting with the time was a great additional touch.
The hexagonal effect when staying up past midnight was cool, but otherwise that event was kind of underwhelming given how much the dialogue built it up (which caused me to explicitly wait for the event). I do get the need to prevent people staying up all night and turning in the butterflies the next day, but not making such a big deal out of it and just having a simple character-driven dialogue event (e.g. “I should really get to bed, I’ll just release these butterflies and head back…”) would probably have made more sense.
Regardless, this was a impressive entry and felt very well polished. Nice job!
