Lawnmower Orchestra

Lawnmower Orchestra is a rhythm game played on a lawn. Norbert is a ride-on mower with a big happy face who cannot stop, so the only thing you decide is which of five lanes he is in. Tufts, hedges, a garden gnome and a sleeping dog called Biscuit come down the lanes on the beat; steer Norbert into each one as it reaches the line and he mows it, and every one he mows plays the next note of the tune over a bouncy 90s rave beat. Mow in time and you are playing the song. Miss too many and he runs out of petrol and has a little nap.

Nothing is harmed by being mown; it is improved. Hedges become dancing dinosaurs, the gnome's beard becomes a bow tie, Biscuit gets a poodle cut and is thrilled about it, and they all join the band along the edge of the lawn. Then the lawn is the whole street and the houses get haircuts, then a golf course, where Norbert grows a moustache, then the sky, where he grows wings and mows the clouds into a duck, a bunny, a fish and a teapot. Each stage is faster, in a higher key and worth more points, up to a thousand times as many on the Moon.

On the Moon Norbert wears a helmet and the aliens dance, and at the end the camera pulls back to show what he has been mowing all along. A run takes under a minute and a half, your high score is saved in your browser, and every run that mows all the way to the end of the Moon wins Norbert something new to wear. It plays with a keyboard, a mouse or a finger. P pauses and M mutes.
