for unity bundles on mac open terminal and run:
cd 'Users/[your name]/[folder the game is in]/Slide in the Woods MAC/Contents/MacOS'
replace [your name] and [folder the game is in] with your actual username and for example Downloads. (or just copy that MacOS folder as pathname) Then, in the same Terminal window, run:
chmod +x "Slide in the woods"
./Slide\ in\ the\ woods
This should work. if it doesnt lmk
