You are in :Tom & Jerry 2013 Games
Usually these kinds of games have only one level which lasts indefinitely, where hardness increases with speed. Such games, almost never become popular, because they are hard on the eyes and secondly - the game is missing the goal. When Tom grabs you and you lose a life you don't have to do anything, just wait for 2 to 3 secs and level restarts by itself.
To play the game only keyboard is necessary. To move, use arrow keys, arrow up to jump. You start off with 10 lives, and that's how many tries you have to finish the game. At the end when you use up your last life, you'll have to refresh the page since 'try again' button doesn't work as it should. This game could be quite simple to adapt for some mobile platform. Anyways it would be interesting to see an iPhone or an Android version.
