It isn’t technically a game. You play it, but it isn’t a game. It isn’t really a toy either, as it is too much like a game. Mind you, it isn’t really a musical instrument, as it’s more like a toy.
There are no levels. No scores. No power-ups. No lives. No bosses. No killing, collecting, jumping, shooting or driving. Just “things” to press and move. And they vibrate. Or jangle. Or whizz or bang or tinkle or hum or clank or plink or bubble. Or all of the above. They record your voice, respond to claps, fly around the screen and bounce off musical leaves.
It really is most bizarre.
