A free app for Android, by Smirnov Sergey.
Ducks and Cats is a collection of four small and easy games. The first one is a puzzle game where you need to select the right color to remove angry UFO-like creatures from the farm! More you hit, more they come! The second one is a driving game where you need to use pedals to stop or go. In the third one, you need to save the cat from the flood. The last one is a cow-bow game for two players.
The collection includes a free version and a paid version. The free version has a 10-minute timer, but you can pay once to control it manually.
