Simple
Graphics were just circles and and square, you could have made the player ball into a ufo or something. Sound was decent, and the controls were simple along with the objective. I suggest that you add a play button or something before you start the game that way you are not aimlessly falling from the start. The 0 point glitch at the end and the increase in life count when you have a negative number is odd(usually it just switches it from positive to negative) adding a life power up would help. Overall this a very simple game, with an almost life like gravity. Not bad for a first try, good luck on future projects.
