What a pity, I only managed to find 3 keys. It's has a good idea, the map's change was awesome!
I'd recommend changing music on the small platforms everytime you are on one. I have hidden paths depending on the music playing so even if there is a path with that music already might mean there is another path when switching music.
i will try again haha ( i was review somethings before ). Thanks for the tips!
at last, i end this game haha.
