Alien Invasion

Aliens are trying to invade earth and you are the last line of defense. You will need skill and good reflexes in order to survive, but maybe doom is inevitable? Can you set a high score against the relentless invaders? Alien Invasion is a classic arcade style shoot-em up with an increasing difficulty curve.
This homebrew game is inspired by the classic Space Invaders, but has some new features. For example, enemies and bullets with different widths and heights.
