This was very fun. If you fail it can get bugged. One time I needed 8 but could only find 6, because after it restarted some of them either despawned, or didnt spawn. Great submission nevertheless.
Thanks! Yeah, I know, I didn't have the time to fix the spawn mechanism properly, so you do fail sometimes. It can happen after you gather 32 too. After some late night debugging I've decided to pass on it not to break anything.
