This is an Arkanoid clone for Atari Lynx

In case you're wondering about the name, Atari console-related software names sometimes use references to cats, which was the naming convention used by Atari (such as for the Lynx, Jaguar, and the abandoned Panther). The game's notable feature is the power gauge, which can be used to spawn helper balls which last for a limited amount of time. The fuller the power gauge, the more balls are spawned. It's okay to lose these, as long as you don't lose the primary ball.
