OMG! I just discovered that Flashback works on macOS!
I loved this game when I was a kid! I didn't get far, however, because I couldn't read/understand English. I may even have had the French version.

I can finally play it through, yay!
@chris I tried playing it then as well but it proved too difficult. I'll definitely give it another try, thanks for the reminder!
