Whilst I do believe that the egg hunting has been extremely well done this year, with both the pows AND egg hunt, there is always room for improvement!
Something that I have found to be irritating is that when entering the mine/realm when hunting, it can often be empty, due to people not signalling when they have already used it. So, here's an idea - you could have an indicator either via a system message, or a little counter in the top corner of the screen (the counter could be influenced by some sort of handheld item like an easter basket, that of the jack-o-lantern), that shows how many eggs are left in the realm. Here's a little UI countdown board of sorts i quickly cooked up in photoshop, to help better visualise the idea! :)
Thanks for reading my idea! :)
