Drenched in atmosphere! The first time I saw one of the spooky things it really got me! The area is so big, I wandered around mashing the radio button and only ever found two relics (and honestly both were by luck -- the radio didn't help much). You've got a really simple and effective formula here -- if you just make it a bit easier to track down the general direction of the relics, and make the scary guys more aggressive, this could be a great scary pacman.
