Collapse is a very addicting arcade game. Some have called it "backwards Tetris, " and I guess t can be described this way. You start with one row of colored tiles in the bottom, then another row comes up, then more. The tiles climb upwards, and you need to prevent them from touching the upper line of the game field. This is done by removing sequences of 3 and more tiles of the same color by clicking on them with the mouse.
In the beginning of the game, there are only three colors, red, green, and blue, and new rows come up at a reasonable speed, so playing is not difficult. As you move to higher levels though, the game speeds up, and more colors are added. You have to become a clicking expert to keep up! And when you can't, there are bombs to help you. You can click on a bomb of a certain color, say, green, and it will blow up all the green tiles. This helps to clear up the mess and get ahead a little bit.
I like the idea of Collapse, the graphics, and the sounds. The only problem I have with it is how addicting this tile-clicking is. They should have put a time limit on it!!
