Firstly, thank you so, SO much for all the kind words. I wish I could say how much they mean. <3
It's pretty hard to market a game about an old internet meme, but I'll keep trying to think of something! Also, you're not the first one to mention the slow beginning. It's one of several lessons I'll keep in mind, if I ever do make another game.
As for the riddle, it's hard to give a hint without spoiling it, so I'll just put the solution here. :P
Also, if you need help finding the 7th key sibling, here's where to look.
There's plenty more to find, and I hope you'll see it all! Thanks again. :D
(Oh, and as for Catie, I wish I had news. the last time I talked to her was back in January, around the time she left Twitter. I'm sure she's doing fine, but I miss her too).
