Tessellation Desolation is a platforming game that offers a challenging suite of gameplay due to is rolling based mechanics. Characters can only displace themselves based on their rotational energy, which is gained based on the shape of a character. Characters are uniform polygons(with one universally breaking exception) built from congruent shaped triangles; that is their design is of tessellated patterns. A state of depravity has occurred wherein characters with greater rotational acceleration attempt to enslave those seen as "rotational-ly" challenged. Eventually one of these less capable rotating characters, an enraged square, decides they will not submit, and their peers are not obligated to do so either. As a square, the player will have to be cunning to avoid and outwit those trying to be oppressive--using their range to latch onto ledges, and to lead on their enemies--until they have disrupted the new order based around the Circle, a figure with seemingly unlimited power.
