The game cheats
It runs fine on El Capitan with Titan graphics card, but it cheats wholesale.
If you play it straight, it is almost impossible to beat. It will self start in the background and eat all your lives - that is a CANNOT SHIP BUG!
It will also “Stick” on a color. I counted 20 black balls in a row before it killed me. It will randomly switch ball colors on you as well - this is another CAN’T SHIP BUG.
It will “jump” the cursor to the other side of the screen shoot your ball there and then snap back. This may be what causes the random ball color changes and yet another CAN’T SHIP.
To make the game playable, you have to reach behind its back and save-off your state. To do this go to ~Library/Application Support/MumboJumbo and duplicate the “Luxor HD” folder. I then rename the folder to something like “Luxor HD - Level 9-1 10 lives 20 coins”. Then when it kills you, you can delete the “Luxor HD” folder and rename the folder that you want to go back to “Luxor HD”.
