The idea is to destroy all the blocks before the song finished.
Trying to get lerping working is a little haphazard - I want the black blocks to spawn explosions- at the moment they spawn an expanding circle with "immovable" set so it should push other blocks out the way (turning them movable when colliding)
'cos it's still work in progress, left click will respawn the ball, right click will spawn the exploding black block.
