Nice for a first run. A tense little scavenger hunt. I was on egg shells dreading hearing that WOMP sound of a light going out somewhere.
My one suggestion: Please put what the controls are somewhere. Maybe a page on the options menu that just says Controls, and then has what the controls are. I was more than half way through the game before I realized I could sprint.
Edit: Bleh, I'm silly. Didn't realize the controls are listed on this main page.
