Clock Tower is an interesting horror strategy game that requires you to complete many tasks in order to figure out the bad guy who is after you.  It's a really good game because you have to really use your head to avoid being caught.  While the graphics and music aren't anything incredibly memorable, the gameplay makes up for it.  I wouldn't say it's anywhere as good as the Resident Evil series, but what you have here is an above average game that you will be coming back to for sure.
