bit spooky for a game about mowing the lawn! lol
fun though. I like that the world borders are solid, you could even expand the game by using different shapes you have to navigate, like an ever rotating puzzle or the spinning bonus stages from the early sonic franchise.
i played for a while and never reached an end screen so i'm assuming there isn't one, which is fine if the game is just to get a high score. but does get a little repetitive quickly.
i liked your sprites, especially the fire with the face.
