If you can remember playing QBert, and would like to experience a similar game, you may want to try SpryJinx. It's similar to that classic game in that it involves jumping from tile to tile, but here the screen scrolls upward, each tile is worth a different amount of points, and there are various powerup items available. I found the computer player quite tough, even at the "Normal" difficultly level. Also, the graphics aren't very good ... but, as I say, if you liked QBert ...
