Thanks for trying this out! Sweet - I'm stoked that you discovered the food sources. I had hoped that was intuitive enough for players to find.
I went off of this example (source code) as the main basis for the boids algorithm, definitely recommend checking that out if you're curious. All of the code for this game is also open source as well though admittedly it's a bit more complex than the Ben Eater example.
Glad you liked the music! I'm also a musician and created this ambient track in Logic Pro for this game. Incidentally this track is also available on my BandCamp page.
