I thought the atari aesthetic of the game was really neat and fairly consistent. There was one bug I noticed where if I jumped and touched my own projectile I would disappear and the camera would fly off forever--mostly just had to avoid shooting while jumping horizontally. I wasn't sure if I won or not--I think I defeated all of the enemies? Improvement would have been for the enemies to be a bit more interactive as a challenge as they appeared to be stationary--I had several hearts but never seemed threatened to take damage. So, mechanics work pretty good, and next step was largely around designing and staging the challenges.
