This is a simple little program that tries to make you learn the layout of the keyboard while playing a game. The game itself is all too familiar, with aliens descending the screen to be blasted.
There are eight boxes at the bottom of the screen and in each one a letter or symbol. From the top of the screen, aliens descend to try and break through the defensive wall above the box. Pressing the key corresponding to the symbol in the box will fire a laser to destroy the alien.
Good News
P. Colourful graphics.
