GoSub

You are a submarine driver in search of sunken treasure off the coast of Cape
Chammawingiwakauguflidplitargoknotz. Your job: Get the treasure chests and be
rich! But there are dangers: it seems the treasures are well protected by
walls and a pesky octopus. Go luck and be careful, Captain.

You pilot your sub through a maze, avoiding touching the deadly walls. Your
goal is to reach the treasure chest at the end of the maze. Don’t let the
octopus completely cover your sub or you will die. Be aware that the octopus
will slow you down so be prepared for a burst of speed once you are past.

The two player game, dubbed GoSub 500 by the creators, is a counter-clockwise
race around an oval track. First to cross the finish line wins.
