1) It’s half the price. (Though 59p versus £1.19 isn’t a huge difference.)

2) It uses touch controls, so you can play it in bed.

Least exciting screenshot I've ever taken? Sorry.

And very interesting thumb controls they are. You use your thumb to move around, but if you use two thumbs in the same direction you can move faster. Seems odd at first – and the pixel art thumb in the tutorial video is inexplicably terrifying – but works really, really well.

It’s a shame it came out at the same time as Tilt To Live, because it’s likely to be overshadowed, but it’s a lovely, lovely little game and deserves better.
