While the art was not the greatest (can't complain much when I can barely use Paint), the atmosphere was rather creepy. It needed a better message to indicate score, as the scream was confusing at first. There is also the problem that you have just a few seconds to play it, and would be hard to get a score higher than 3 or 4 in that time. This short amount of playtime also means it becomes repetitive fast,
It reminds me of the Egyptian myth of weighing hearts. With some major improvements in the art style, it could be pretty good. You could even put people's sins on the scale.
