Grab the Beetom and freeze it to extend the runway at the top left door; this is easiest with HiJump disabled. It is optimal to leave a half-tile gap in order to extend the runway as much as possible. After freezing the Beetom, it is possible to go down and farm, while returning to refreeze the Beetom.
