Tessoryn per mle256841

Tessoryn is a quiet spatial-assembly game with eight authored sculptures and three to seven asymmetric pieces in each. Rotate a piece by quarter turns around world X, Y or Z, select its socket, and place it only when both position and orientation match. A translucent reference ghost can be switched off for a memory challenge. Drag the independent camera to examine every side.

There is no timer or score. Wrong placements remain available to correct. Sculptures unlock in order; changing sculptures starts a fresh attempt. Current pieces, orientation, ghost preference and unlocked sculptures are saved locally. Close or leave to pause, and reopen with Resume. Brief rotations and the completion orbit stop under reduced motion.
