Very interesting, yet challenging. Finally got stuck at a later level and couldn't go any further. Therein lies the rub: there is no menu structure or help/walkthrough function. I refreshed the page to look for a menu, and all of my progress was lost. Not cool. Other than that, well-designed atmosphere, good gameplay and controls. I didn't have my speakers turned on, so I can't comment on any music or sound f/x. I was really interested in seeing how the game ended, though, but I didn't really want to have to play all the way back through. Quite the achievement in under 48 hours (and by one person!), but still plenty of room for improvement. All in all, keep up the good work! And thanks!
