That game is based on Macromedia Director. When it loads, it goes to 640x480 - not sure what refresh rate though. Shows up ok on my display but trying to switch from fullscreen just makes the display blank and it modifies the preferences so it always stays that way.
I can't see any settings to let you manually change the output - the preferences are all stored in binary. Plus there aren't any display options in the game. You can play an online version of that game:

Kinda like a Where's Waldo for random objects.
Your best bet would be to get a better display or if you have an Intel Mac, run the Windows versions in a VM or through Crossover. If 1024x768 is your native resolution, a bigger screen is recommended. You can get a 1680x1050 for close to £100 these days and the Mini will drive the display ok.
