Nice use of boid flocking to "shoot" the enemies. The sound effects could have definitely been lowered. When you get a bunch of boids going it gets kinda grating. I also felt the zoom was a bit too far and made it hard to make out my character among the triangle boids and to make out the enemy bullets. I think if you added some more enemy variety, added a way to lose boids such as after they do X amount of damage/blocking then you could have a pretty interesting gameplay loop going.
