Hardbounce is a jumping game where simple design goes together with very challenging gameplay. You’re a ball, rolling around a series of black boxes that, slowly but surely, are moving towards a spiked ceiling. If you push the down arrow key, you switch boxes before that happens. If you use the left and right arrows, you can avoid other deadly objects in your path. But push up and start bouncing, and the obstacles have to fear you! How far will you bounce before you fly too close to the spikes?
