Same for my side, my main issue is getting the flocking work nicely but in the end, time ran out and had to cut a lot of features ( wanted a shooting feature and add a bee boss). Sadly time didn't allow us to do that, so we ended up focus on getting the game to be playable.
Nice, rare to see someone who knew about this game.
Don't worry, your game concept is interesting and fresh, just need extra time to polish the rhythm system, as your game relied heavily on "behind the scene" side (beats, sound, timing) for your game to work.
All the best to your future improvement too, I will be improving my code and fixing the game after this voting (especially those small bees).
