Spot the Difference

Umbes

10 pairs of pics with 5 difference to find in each pair. Reviews are greatly appreciated. I'll be making another spot the difference game, so any decent suggestions will be implemented. 22-11-03: added continues, modified timer, stopped cheating (hopefully) To be implemented in the future versions: - sound - some way of selecting different levels on different plays or maybe having random levels - a submission system to an online high score table - an on-screen reading of the number of differences left to spot in the current picture (?)
