My friend and I made our first ever published game. It's available for free on Android devices from the Google Play Store.

Play as one of several epic ninjas each with a unique ability to help you progress through the infinitely side scrolling level to achieve the best high score. Run, jump, slide and climb your way through an infinite combination of level segments. Special abilities include grappling hook, speed burst, dash, wall climb and glide! Collect coins on your way to purchase upgrades and improves your ninjas.
