Nice concept, though the maze felt like the tutorial level to a longer game. I liked the idea of picking up 'sight' objects that reveal the true nature of parts of the maze - it was reminiscent of Soulblazer and Illusion Of Gaia in that respect. I think adding a health meter would have improved it as I wasn't sure how many times I could be attacked.
(Also, it worked in browser a lot better than I expected!)
