I distinctly remember playing this on armorgames.com. You went around this house cleansing it (i think) of evil spirits. You could only see them if you wore some kind of mask. You knew where it was when you found a half eaten rat on the floor. I cannot for the life of me find it on the site anymore. I don't remember the name to even know if it still exists anymore.

Don’t try to take on giants like Google Shopping or Shopzilla. Instead, find your niche — one that you’re already familiar with — and start small. Examples of smaller niche-centered price comparison websites are Gocdkeys that compares gaming products, Pricechecker which compares UK prices, and Farecompare that compares flight prices.
