Bravo!
As simple as ingenious, albeit too short - as mentioned already, and arguably too simple - with latter being understandable factoring former.
Nevertheless faved for the pure elegance of concept and execution.
Bravo!
Verily, this is one of truly marvelous gems in games history. So simple, yet so elegant. Ghosts, zombies, aliens - bloody posh! This is the real fear, and the real thrill too. No amounts of cheers and kudos can be granted to this unusual and bright wonder's creator to truly gratify such creativity and repay for brilliant shades of joy it gives.
And yes...
you have to wake up.
