Why are you running, Philibert ? is a game about Philibert.
Philibert is running.
However, Philibert cannot climb or explore the depths of 3D space, so most obstacles tend to impend his progress towards... who knows what. If you feel like it, you can help Philibert to reach... uh... plenitude ? Freedom ? The right side of the screen ? Certain Death ?
By using the arrow keys of your keyboard, you'll find yourself able to target and displace platforms around our hero.
That might help. Then again, it might not.
