Once in a while I go on Home of the Underdogs to look for a little-known game just to pass the time. There are so many little obscure (even Flash) games that are really terrific, but that we'll never play.
I hope that people will post their favorite obscure game so we can all have a look. No point in saying "I know that game, etc...etc...", this can just be a post where someone can get some good ideas for a new game to play.
My entry is Jumper. http://www.the-underdogs.org/game.php?id=5011
It's a fun game using the Game Maker engine. Give it a try, and post your entries here, too. I tried searching for a similar post, but I didn't come up with one too quickly.
