Hold click to widen.

Press rightclick to shuriken.

The score system is to make a long combo without taking greys, first block is worth a single point while each consecutive block becomes worth 4 more points up to a maximum of 200.

Since greys remain in permanently you have to use shuriken to remove them. This comes at a 777 point cost.

Bonuses:
- Stealth (30% bonus): hit no greys
- Clean finish (25% bonus): have no blocks on the board at the end of the track
