I'm on Android and it's asking me to download additional resource files

The app "Lucky Patcher" can cause this issue if you have it installed on your device. Uninstalling this app should solve the problem and let you download Fun Run from Google Play.

If this isn't what's causing the problem for you, you can get the newest version of Fun Run from our website: http://dirtybit.com/apk/Fun%20Run.apk
