Level 2 is possible to get a 1:02 maybe a 1:01 with perfect routing but the timer will not let anything below a 1:02 show apparently. You need to bang Garfield off of everything possible on the ground while holding right and getting as much low hanging food as possible. Level 5 is possible to save a second with a glitch that causes Garfield to take damage when you jump because you jump right before a hill and enter the ground of the hill and get stuck on the way out of the ground causing the game to think your taking damage and will damage boost you up the hill. there are 2 ways to finish your damage boost on the hill. with a rapid jump which will cause Garfield to jump at the end. The other way to end it is by just running it out. There is no set faster way so far, but I personally believe that the jump allows you to go slightly further and could help make a more noticeable difference
