Gameplay

A player controls a curve which destroys entities upon collision. There are four set of 'control' points the player can move. The two points manage the endpoints, and the other two points refine the curve.

There are two entities in this game, which moves at a constant rate toward the red circle: the green square, which must go to the circle and not be destroyed, and the red cross, which must be destroyed before it touches the circle. Points are scored for each successful entity. The game ends when an entity is violated.

More entities spawn as points are scored.
