Thanks for playing and very sorry about crashes and poor instruction (o_ _)o.
In this game, you help move the bricks to avoid big ball. You can get close to bricks and pick them up, then click somewhere to throw them out. You can also throw the bricks to the ball, that will become an effective counter measure and cause damage to the ball.
The reason of crash I think, is when the ball gets hurt by ice brick and gets frozen, approaching it will cause the crash. Should be fixed in latest version after the jam.
Thanks for playing anyway. Have a good day!(´︶｀)
