Let me start this blurb by saying that the title is a lie. It's not raining anything. It's a single dog falling through the sky while cats and other things probably not in line for household pets or foreign bistros are floating around. But It's Raining Cats And Dogs is a much nicer name than, say, "Puppy's Plunge Into Oblivion" for this simple arcade title from Umut Dervis.
The controls are so simple that the menu screen is enough for you to grasp them. Move the falling dog with your mouse and bounce off the various creatures that float past. The aim is to not drop off the bottom of the screen, build point combos by hitting the same creatures in a row and avoiding some critters. Last as long as you can and get as high a score as a plummeting canine can achieve, bouncing off the occasional fat (alien?) cat for a score bonus.
It's simple and addictive, the hallmarks of any good 'keep going as long as you can' game. It's fun, it's colourful and it has a cute soundtrack. Really, more does not need to be said, other than some at JIG Towers speculate that this would make a great iPhone or Android game. No argument there.
