This game was the 'Winner of the 1982 Arcade Alley Award', which just goes to show that things have moved on a lot since then.
Not that it's a bad game. The scenario - a Mad Bomber dropping fizzling projectiles which you must catch in your buckets - is amusing and the graphics are pretty good. But there's just not enough to do to keep you interested. Given the price, you might justifiably expect a lot more.
