I actually enjoyed the sound and music. It has a great retro 8-bit feel to it and it felt nostalgic for me </old>. Also makes me wish we had more time for me to try a retro theme for the music in our game rather than just scrambling to play/record guitar and bass tracks.
I think the cooldown gives you a sense of urgency and resource management which is nice, but maybe the people require too much damage to be.. juiced?
Alternatively, maybe the logic behind the number of people that meet the criteria and the probability that two people matching that criteria will have a "golden moment" where they will be in the same position at the same time?
Again, great work, I definitely enjoyed it.
