Thanks for playing!
The blur orb represents your special BATTY VAMPS power: echolocation! Press F, LMB, or A on gamepad to see through walls. It's helpful for finding humans.
In the future I'd like to make a full city to fly around in. I also want the humans to have real AI so they act normally until they are aware of Batty then have a fight or flight response or raise the alarm. So potentially it could turn into a bit of a stealth game. I have technical hurdles I have to overcome before I can get there though.
