The idea is pretty simple, you've got different coloured blocks coming at you from right, left, up, and down. As soon as they get close enough to you, your toast. You knock em off the board by shooting the coloured blocks with the same coloured disc that your little space ship fires. You change the color of your disc by hitting a different coloured block. You get all that? The game even has a campaign mode that starts off easy and progressivley gets harder and harder. There is a settings menu where you can select your variables, depending on how hard you set the game to be the more points you'll rack up, it ranges from 38 points per block to 93 points per block.
Colours Pro is a great thinking game, you won't realize it when you first start the game, but pretty soon you'll have to figure out a game plan to stay alive. The graphics aren't much to look out, they're well done but nothing fancy, there's also some nice background mod's that are playing. The whole point of this game isn't lush graphics though, it's meant to provide hours of hair-pulling entertainment. This game was very well thought out in it's design, and is very original, I've never played anything quite like it.
