Submarine 1: The Basement is one of those point-and-click "escape room" Flash games that were popular during Flash's early heyday. In the game, you are stuck in some kind of underground labyrinth and you must figure out how to get out of there with barely any clues to help you.

Luckily, Spikestuff knows exactly what to do and more and gets to the surface in record time.

There is also an alternate encode that expands the map for better comprehension of what's happening.
