Converted from the original Python game from https://inventwithpython.com/pygame/chapter9.html. Some levels are pretty tricky. I provided the solutions (level 2, 3, 6, 7, 8, 9) at: https://www.youtube.com/watch?v=xUCS4msbFNg&t=8s For level 4 and 5, I haven't solution yet. If anyone could solve, let me know.
