Lol, no...
You think you invented the idea of beating the game on this mode? It's not even an idea, it's just something that automatically goes with the mode itsself...nobody suddenly thinks 'WOW i've just realised, the game can be beaten!'. Except maybe you.
Off topic, where do you get the key of inversion on whatever the translation is-the key to the door that's in the mirror mode parallel in the 80s level? I assumed it would be given for beating the game in mirror mode, but I just did that and it doesn't give anything at all.
