Thank's for playing it and commenting - its appreciated.
You've hit on two mechanics I was thinking of working on - making the jittering worse with the death count (or insanity) and hinting at possible paths. I gave up on the former as the css animations are bloated already and I couldn't think of an elegant way to add several states short of repeating the animations. If I could nail that I could see using the structure on other 'stories'. As for hinting, I felt this could be easily managed as an array of clues (ie. "hungry for bugs", "play word games with yourselves" - terrible examples but you get the idea?), only I couldn't think of a good way to present them. Something to work on perhaps?
