If you know Arkanoid, you already know what this game is about (and by the way, if you don't know what Arkanoid is, you've got a problem! ).
Joking aside, Nannoid is a decent Arkanoid clone with more than twenty different levels that challenges you to break all the bricks in the wall without letting the ball fall off the paddle.
Luckily you're not alone in this mission: you can count on several extras and bonuses that help you successfully complete your tasks. You'll get also extra points for exploding all those "weird floaty things" (as defined by the author) on each level.
Summing up, Nannoid is a simple, fun game that's perfect for a short, relaxing break from home. The only drawback is sound effects, which could be greatly improved.
