A pretty fun game! I like to think of this more like a sandbox. I collect enough nectar to get the next hat and see what it does, and then do it all over again. The game could easily have "stakes" but it doesn't need it. It's just a chill game where you fly around and collect flowers and that's perfectly fine.
At some point when I got the hat with the monocle I couldn't re-enter the hive for some reason and I made sure to triple check that no other flowers were missing so that might be a bug. But there should be some indicator at the hive when you've gotten enough honey (maybe the honey spilling out of the hive doesn't show until you get all of the flowers!)
