Choco Chiptune. Ancraft (4/6/7/8; 640 notes on Oni)
Starts with half speed and twice again during the after-chorus bits. The song may be fast (210BPM base) but not too rowdy with mostly single-color clusters and 8th chains, and none over 16th separation (although apparent 32th at half-speed), all following mostly to the percussion at the back. If you can cope with the speed it's rather nice piece of chocolate cake.
