Just a learning project for right now.
Space bar, click or touch to thrust upwards.
Tap or click Swoop to fire a missile.
After 10000 points a new type of enemy appears. If you shoot him you gain 5 missiles.
After 20000 the thief bird appears. if he touches you he steals 1500 points.
I might add some more enemies and shield power up that is a little bird that circles you for 30 seconds. Thanks for any feedback.
