This was my first virtual world created for the Building Virtual Worlds class. (What is B.V.W.?)
It is a very short game in which the player stands in front of the projection screen and uses her shadow to guide a toy kangaroo who is trying to escape from a creepy baby. When the kangaroo encounters an obstacle such as a flowing stream, the player must use her shadow to build a bridge over it.
Hopper's Escape was extremely well-received, even prompting our usually-reserved instructor Jesse Schell to exclaim, "Oh man, I'm in love!" In particular he lauded the use of dual game modes (guiding hopper; building bridges) that were "both novel and interesting." Hopper's Escape was featured in the end-of-semester B.V.W. Show.
