Vong

Vong is a homebrew game that plays like the classic arcade game Pong, but vertically instead of horizontally. Vong features six gameplay modes, two of which are hidden. The normal modes are:

Game 1 = Single Player
Game 2 = Two Player
Left Difficulty A = Small Paddles
Left Difficulty B = Large Paddles

Easter eggs:

In single player mode (paddles can be large or small), if you hold the paddle button, it becomes impossible to score on your opponent.
