I made a game in January 2007 called 'River Crossing'. It is made in the style of old Game & Watch LCD games. In it, a small man must try to cross an endless series of rivers.

The game is really not very enjoyable but on the plus side, it has one-button gameplay. So you can play it with your penis. If you don't have a penis you can play it with a finger, toe or really any part you can thrash against the space bar. You can do that even if you do have a penis, it's actually a preferable way of playing the game. I'm going to stop typing about penises here.

I may ressurect this game because it is simple (read: crappy) enough to be remade in a lovely GUI suitable for anyone.
