This game is really great, but it doesn’t seem to be maintained anymore. I haven’t seen an update in forever, but I was still able to play it for a while. However, upon updating to the latest iOS version (15), the game crashes as soon as the menu screen appears. I saw some other comments about this same glitch, it does seem that it just doesn’t work with iOS 15+, as it still runs perfectly fine on my iphone running iOS 13. Great game overall, please update it to work.
