> The time for coming up with an idea, making a design doc, compiling the game and publishing it etc. does not count in the 3 hours you have
I think 3 hours is short enough for making a game without having to worry about making the page too!
Great job with this - I believed "one more level" each time I saw it and kept being surprised by how much content you managed to make. The music, art and gameplay all worked together nicely too.
