Pretty fun to play. A really good job for a 3 days game jam, and made by one person! I noticed a few things you coould check out though: on my first try there was a time where the ball went out of the stage, I reloaded the page and then got to the last level, and there was Bill wishing me good luck, but there was no way of completing the level. I'm not sure if this was intended or some kind of error. However, I should point out that you managed to develop a lot of physics based mechanics that work very well with the whole golfing gameplay. Awesome job! Really :)
