I absolutely adore the concept of a Tales From the Crypt-style point-and-click adventure, but this just doesn't do it as well as it could. Creepo looks great, and he supplies one or two excellent bad jokes. And the art is very nice, especially the backgrounds. However, the puzzles could be a bit harder, and, as Geminate said, it just wasn't spooky at all. At no point does Crazy Mason make some sort of ominous appearance, and you don't even know what he looks like until the end.
Overall, a good concept that needs to be executed a bit better.
