Congrats!!! Sounds like people are really enjoying it, and it's nice to see that your traffic/sales are holding strong a week later! The Sapphire Safari collaboration in particular seems like a great idea while both games are topping the charts.
I'm definitely looking forwards to your next project, whatever that ends up being! (I imagine you can guess which of the ideas I'm most interested in, but don't let me sway you too much, haha. They all sound good!)
