DTET Rotation System

The DTET Rotation System is the rotation system used in the fan game DTET.

This is how they appear to rotate in free space. What I suspect is actually happening, is that the pieces are rotating through 4 unique positions, like in SRS, but always prefer to be touching the bottom of their bounding box, like in TGM rotation.

Pieces spawn in the center, (left of center for the odd width pieces) with their topmost solid block in row 20.

Wall kick is yet to be fully described.
