I’ve just released my Jumper! Infinite Runner template on the asset store. I hope some of you find it useful! I’m more than open to any suggestions/feedback for features you would like to see.
STORE: Unity Asset Store - The Best Assets for Game Making
DEMO: http://losttitle.co.uk/unity-demos/infinite-runner-template/
Code is fully commented and comes with all the code required to integrate Google AdMob/Google Play Services out of the box, just follow the instructions in the README.
Thanks for checking it out!
