This is a solid start to be sure, I had fun playing. Local or Global high score would be an awesome addition, and maybe have the environment evolve as the score goes up? Kind of giving it a feel of visual progression to go along with the higher score? I don't know what direction you are thinking about going with this but just my initial thoughts. I got drawn into this one for a bit, I know it's not crazy but I had fun trying to improve my score. I'll come back after the submission period to give you a rating!
