From the developer:
SplatTestDummy is a fun fast-paced retro arcade action game. The atomic fish are taking over the waters, and it is up to you to remove them. The game is simple to play, but difficult to master. You need to splat as many of the critters that swim onto your screens as possible. Greater accuracy, speed, and efficiency increase your score.
You may want to check out more software for Mac, such as Qwak, Plantas VS Zombis or DROD KDD, which might be similar to SplatTestDummy.
