New big map, music and bug fixes.

Hello!

I have published another release of Wizards with Rockets. This release is significantly different from other releases thanks to the new map! It is a full singleplayer map that you can complete.

Also, you will notice new music! It was randomly generated with Wolfram Tones. A surprisingly acceptable tune.

Another thing I hope I have fixed is the AI going out of bounds. They should now stay within the bounds of the map and their collisions should be working properly now.

Things still to implement:

* Checkpoints so you don't have to traverse the whole map again

* End of level event - show a game won screen

* More levels
