U have to save the cheese from the different enemies like lizard,ant,mice,cockrouch,worms....you have to bust them....U can tap and kill lizard,ant,cockrouch and worm.....but mice can be killed only by catching the cat icon....ant can be killed by swiping because they move faster.....catching bomb will kill all bugs except ant and mice.....catching turtle will slow down the gameplay for 10 secs.....so bust them and have fun!!! enjoy gaming!!!
