Fly your helicopter as far as you can.

This is a very simple game: you control the helicopter by tapping the screen to go up and releasing to go down. The goal is to dodge your way trough a cave, flying as far as you can without touching the walls. When you collect 8 consecutive stars of the same color you get invincible for a short period of time.

There is a secondary mode, where you have to advance into an enemy territory while avoiding fires.

This is a game I did while trying to do some dynamic light rendering in 2d.
