So I came across this post the other day on Apple this. There is somebody over there who is a brand new audio game developer. They have created a game which is similar in style to the castaways game made for the Windows PC. However, this is on iOS. The game is currently in beta stage, and if you are interested, you can use the links provided in that post to download and try out this game. Please know that there are currently some bugs which is to be expected with beta software that is just beginning development.
