Need a simple Endless Runner Game to be made that will work with Android and iOS. Will need to generate Ad revenue and have a top score database within the game. In App purchase is a bonus: this can be added at the end if possible. Things to be bought are stuff like extra lives, boost or faster characters. Program code should be done neatly with comments if possible. If the price is too low than it can be negotiated higher depending on experience and quality of game that is produced. This will lead to future projects. Be in touch if you think you can help. I need someone trust worthy and has a good enough grasp of English to finish the project. Thank you for your time.

I have an IOS app that relies on the microphone. The app has worked well since IOS 7. In IOS10 the app now crashes on startup. I have added the plist permissions description now required in IOS 10, but it still crashes. If I delete and re-load the app on a devices: the first time the app starts correctly, I am presented with the "Allow Microphone", I hit yes, the app completely works. All subsequent attempts to open the app then fail - It crashes immediately. If I go into the devices settings and disable microphone access to the app, the app will then open. I need help troubleshooting and resolving this issue.
