Space Invaders is a remake of the well-known Midway/Bally game first released in 1978, but with a twist. You can download all 71 of the Crozza Remakes here.

Like most of Crozza Games remake, the gameplay is accurate, but the graphics and colors are different. Speaking of different, the twist mentioned is four different wave patterns. In other words, the aliens always move left and right but with four different possibilities. There's no way to define what they are, so just choose 1, 2, 3, or 4 from the main screen and see what you like.

Otherwise, the game starts out slowly as you remember and gains speed as you progress.

F4 will switch from full screen to windowed mode. Arrow keys to move, space bar to fire. Like all Crozza Games, the game is portable, so no installation is needed.
