When the theme for this GWJ got revealed I was hoping someone would do boids (my take on boids was last jam) so that I could compare - gotta say yours feel a lot more snappy to control than mine ever did. For what it's worth I didn't find the colors too overwhelming (though after the warning I did elect not to maximize the window like I'd usually do, so that might be a factor). I appreciate the inclusion of a tutorial (one that managed to be useful despite Show Don't Tell wildcard, even!), and while the game's on the short side you managed to get a decent bit of variety in there. Small note - the game seems to skip past the title screen as soon as its done loading?
Oh, and +1 for the menu background attract mode :]
