Physics is the core of this game. The drag and drop mechanic lets you stretch the elastic to launch the ball. You must aim to knock down targets and conserve your precious resources. That is the main loop.
Playing involves dragging the ball. You then release it to shoot at the targets. Use the explosive TNT boxes to take down multiple targets at once. This helps you complete each level using as few balls as possible. The fewer you use, the higher your score will be. It is a strategy game, which is kinda weird anyway, and you need to conserve their precious resources for future challenges.
