Very cool entry once I figured out what was going on!
I know it says food and such, but I thought all of the brown points were islands at first so I played 2 or 3 times wondering what I was doing wrong lol
Once I figured that out it was quite fun leading my pack along to grow larger and larger while keeping away from or fending off other groups. I think I basically played pacifist until the end where we had to take out the last other group.
Very good job on the controls, animation and flocking behaviour! If you just add some even premade music and a sound effect or two it would heighten the game and the play so much!
