Well, the store has changed a lot since iOS 10, and launch weeks are more challenging. Launch numbers are down in general. The game currently sits at 212k downloads and $9k USD (ads and iap included) after 3 weeks. I don't typically share revenue numbers, but as a 'state of the union' of the current App Store, I think they're useful. Devs really have to make sure their monetization is as solid as possible nowadays and the ad to fun balance has to be tight.
I do think the game is suited for a decent revenue tail being level based, and I'm adding levels pretty regularly. That compulsion to see the next level is an asset. Hopefully with some future features it'll keep trucking along.
