This was from the Mystery House Taken Over competition, where IF authors were tasked with revamping the old, famous adventure game Mystery House.
As far as I can tell, this game only allows directional commands, and all that happens in each room is that a piece of original, poor quality line art is replaced with a piece of badly cropped clip art as a joke. I found it amusing, but the game is so small and light as to be hardly there.
If anyone finds additional content, let me know and I'll revise my review.
