Although written in Python, it is close enough to VB (atleast VB.NET) that hopefully you can get something out of this. Jump from platform to platform as the Earth falls away from below you. 6 different worlds, infinite increasingly difficult levels.
Cause its python, there is no EXE, simply install the Python + PyGame runtime, and run the game. Open the game in notepad to see the source code.
Don't worry about the runtime or gfx lib being viruses or anything. If you want proof that they are real, Google will show you plenty of examples as they are both rather popular. Enjoy...
It also has a demo mode and some good music (used with permission) btw
