Hello, I'm xPathfinder who's the developer of 'Ace of Protectors'.
I'm here to tell you something to Mac OSX users.
Currently, I found few graphics cards might have a problem with launching.
The problem is,
When you launch 'Ace of Protectors' in Mac OSX, you may see only white full screen.
Actually, The game is working well, just shows only white screen.
For this,
First, Go to Desktop Screen by using Command + Tab key or whatever you want. (Don't terminate the game during this work.)
Then, Return to Ace of Protector's Screen. This will work and you will see the game's main menu.
If you have any problem, Please add and message me.
