Here's a small puttputt game I created in java. Has an online level editor for creating maps, and highscores whenever the highscore server is up, and I get around to debugging it...
Instuctions: To play, simply click the ball and drag away from it. The farther you pull back, the more power will go into your swing. Each course counts the number of times you putt, and you also have a cumulative score. It's not quite finished now, but I think it's the most complete out of the projects I've started. I plan on having different obsticles and things, but for now it's just blocks :)
