Game was fun towards the end but maybe started out a bit too slow. I think one thing you could add post jam would be maybe a mini map. That way the player can strategize their path better to protect the gnomes. Also rather then the clock counting up forever, I would make the grass more aggressive and count down from 5min or something to reach a win state. I really liked the little polish details like the sound the lawn mower changed based on speed, the trail effect of the character, the little arrows on the edge of the screen. Well done!
