This is a cute valentine and a nice use of flocking. One suggestion is to have the hearts flap their wings like butterflies. The hunter mode seems underdeveloped. Poor use of space on the right hand side with the buttons.

Cute! Maybe you can let the Hunter self controlled (random), or chasing the hearts.

The flocking behavior is well-done.

The hunter should have predatory AI behavior.

Kind of want the Hunter to move on its own like Pac-man to try to eat the hearts…it could open and close it’s “mouth” like Pac-man… Also would like to see some meaning in the colors of the hearts. Nice idea for a valentine!

I feel like this could be a nice screensaver if there were a mode where it just automatically spawns new hearts and adds food and stuff and you could just sit and watch it go.

I agree that I’d have liked to see a mode with a bit more autonomy in this demo (“screensaver”-esque). Maybe if you don’t touch anything it just loops after 30 seconds or so through each mode? It seems like there’s interesting things that you’d see at the transition between modes (because you don’t restart the simulation when the mode changes – a huge plus of your work.) -SB
