Nice shooter, but I found that clicking wouldn't shoot. I eventually figured out that holding the spacebar would continue to fire. The lob of the shot also made it hard to hit anything.
Interesting... it should be the left mouse button. I don't know what happened there. Yeah, the arc is difficult to use. I was intending to avoid the typical hyper-aggressive feel of a shooter. Nice boid implementation btw!
To clarify the controls issue. Rapidly clicking the left mouse button did not fire lots of projectiles, it did almost nothing. Holding the button did work.
