Yoko & Yuki: Dr. Rat's Revenge

\"Yoko & Yuki: Dr. Rat's Revenge is a family game suitable for kids of all ages. Yoko and Yuki are two adorable cats in love with each other. But the devious doctor Rat stole Yuki from Yoko. Now it’s time to do some cat business — to save the girlfriend, using helpful gadgets and finding the solution for any puzzle. That is no ordinary cat — our hero is equipped with scissors to cut ropes, gravitron to flip the world and spray can to find hidden objects. And the game gets harder and harder with new puzzles and challenges. Daring players would be handsomely rewarded for using their wits and helping two cats to achieve their happiness!\"
