Extra time
When you are in the level plantfood, there is an easier way to beat the timer to get a gem. when the timer first starts keep going until you get to the bonus level. jump on the platform and when you get to the level, just jump over the edge. since it is the bonus level, you will not lose any lives. yuo will just be standing next to the platform but you should have about 1 minute and 43 seconds added to your timer. NOTE:if you die after you get the extra time, the timer will stop and you will have to reenter the level to get the gem.
