Phlipple by mal1ce is a unique puzzle game. The goal of every level is to reduce a 3D shape to a single square. Elimination of squares is done by flipping edges around just like in a cardboard box. It starts off relatively easy to teach the basics just to later on serve hours of brain tickling fun.
