AJ – THE RUNNER AJ – THE RUNNER is an arcade platform game where you control a running boy named AJ. The objective is to try to take AJ as far as you can through a maze filled with dangerous corners. Gameplay in AJ – THE RUNNER is very simple (as usual in games developed by UNITY ), but that doesn't mean it's easy. In fact, nothing could be further from the truth. Lasting more than 120 seconds in a AJ – THE RUNNER game is a challenge that you'll have only your fingertip to get you through: tap the screen once to make AJ Run away, tap twice and it will change direction. It's that simple asnd yet so complicated at the same time. The desktop version of this game can be controlled by mouse or keyboard. Main objective of this game is to increase the concentration power.
