It misses player feedback, I was shooting the drones first until I saw the boss health. Then I shot the boss. Great design on the boss btw, and the turrets really got up in there!
I'm glad you liked it! Yeah, the end of the jam was kind of a rush so I wanted to prioritize the game being playable (and I'm not sure how I would have feedback that the drones aren't getting damaged, so I just stated that they were invincible in the controls on the game page).
