I had a planet about 150 times larger than the sun. I accidentally lost track of it, and it hit the sun and desintegrated. Something doesn't seem right here...
This is a GREAT, incredibly good looking, and easy to use music creator. Unfortunately, it is very difficult to create a perfect song because many songs have additional sharps/ flats not in the key signature, which brings me to the one thing I would like to add. This tool would allow you to turn certain notes sharp, or flat. It could possibly be used by clicking the tool, then selecting a square. It could be indicated by adding more, or less transparency on that selected square.
Make a survival mode when you finish the game! Enemies could continuously come at you, and then the bosses come in, and they keep getting stronger! It would keep the game more fun after you beat it :D
