Took me a minute to figure out the controls and how to jump midair, but after that, I enjoyed the game much more! It is very challenging but had me trying again and again to get a higher score. I did notice that I never really used the shooting mechanic because it was too much to juggle with the movement mechanics. Other than that, just work on communication and responsiveness to different events in game (like loosing health?) and you've got a solid game! Good luck!
