I guess I am the only who played this so far, because I only found my eggs =D The concept is great, and I cannot even fathom how it works on the server side, really impressive. It would be nice if there was a way to discern between eggs though, as it is not it's absolutely based on luck. Maybe give them a different way to "glisten"? something that is hard to see, and put the seeker on a timer so sometimes going for an unsafe egg is necessary?
Anyway, cool idea!
