Took me a couple tries to fully understand the game. First death was to not realizing that each button press flipped the direction the character went rather than needing to be pressed repeatedly like a Joust or Flappy Bird, second was to hitting a flying saucer to see if it'd do anything since only stars had been mentioned, third was to hitting an asteroid because the screenshot made it look like you were supposed to jump from rock to rock somehow. Once I realized the only thing I was supposed to touch was stars and that I was on the clock things went much smoother, heh.
All that being said, it's a cute and fun little dodging game with some pretty tricky setups, especially with that time pressure. Good work getting it together! :)
