This is a simple experiment to test collisions in pygame.
The game is a minimalistic 2D airplane simulator where the player can move the airplane up and down with the arrow keys.
Mountains are randomly generated and the player must avoid them.

↑ or w — Move the airplane up
↓ or s — Move the airplane down
← or a — Decelerate the airplane
→ or d — Accelerate the airplane

Esc — Quit the game
Space — Restart the game (when the game is over)

To win the game, the player must avoid the mountains and land the airplane on the ground.

This program uses a simple collision detection algorithm that checks if two polygons are overlapping.
The algorithm is based on the Separating Axis Theorem.
