Couldn't get the Mac OS version to run on Big Sur 11.3.1. I get a You do not have permission to open the application “CaveSlime” dialog when I attempt to launch. Didn't solve it with moderate amount of googling.
Fun game. My platformer skills have waned, so I didn't finish it. Maybe it would have been easier if I was using a controller and not the keyboard. I like the graphics and dramatic lighting effects. Keep it up!
