I made an iPad game. I then made it work on iPhone too. It took me 5 years to finish. I liked it. People who played said they liked it, but it only reached a tiny audience even if I did some paid advertising and used all the traffic of populationpyramid.net to promote it.
Now, it’s not on the App Store anymore, because it did not make sense to pay an Apple account for less than 10 downloads/year and the notch of the new iPhones felt like too much pain to handle for a symmetrical gameplay like this. 🤷🏻♂️
