I replayed it today actually because my team still hasn't submitted our ratings yet, we are doing relative sizing so we are compiling all our feedback so that we can fairly distribute scores to everyone. I did see demon heads this time. I also figured out the tag feature. Super awesome, still just as fun the second time around. Really really solid throwing mechanics, I really liked the graphics, like they weren't insanely perfect or anything but they felt perfect for what you were going for. I would say definitely make it into a feature game.
Edit: Wanted to also say great job on the audio. The spatial audio made it really easy to fight off the hordes coming from many directions, and I liked the music too.
