Hello I don't get access to the game! only a pink frame with music but not possible to access it. Is there a problem with the Mac version?
I figured out how to work around these kinds of bugs. If you hear music and SFX that responds to your movement but see only black or pink, try ESC then Options and reducing the Quality or Resolution sizes. Play around with those whenever a problem, Apply then Resume game. Sensitivity tweaking helps too depending on your mouse. It worked for me!
