His Virtual Boy project “Real Danger” is a simple game in which you are controlling a rabbit, guiding him away from the diving eagles who are out to get him. The eagles get progressively faster. If the rabbit is caught, you can press A to try again. It is based on the gccvb dev kit.
The dev kit used is the outdated 1.0 release of gccVB, but the game code is very clean and good for learning.
