Lightmare is the latest release from Edit Mode Games (aka Kevin Oke). Like Kevin’s other games (most notably, the Robotron-inspired satire Consumer CULTure), Lightmare is simple in concept and execution, but saddled with ample amounts of charm. I really like this description of one of the obstacles in the readme:
The goal of the game is simple. As a hungry vampire, you must avoid light and cars to reach the vial of blood at the end of each stage. Apparently man-made light hurts vampires as much as the sun does! That’s got to make life difficult for a modern-day bloodsucker (and for the people playing as one in a video game).
