From the developer:
PapiMirror is an arcade dexterity game for Mac computers. Press LEFT/RIGHT keys to move Mr.Papi (red ball guy) in the left side and avoid spikes. The Papi in the right side moves to the opposite direction as if a mirror exists between them. If the Papi in the right side catches a coin, you get a bonus.
