I am playing the Windows version. I've found 5 pillars but the red door in Humanoid world is not open. I think I need to find a sixth pillar as there seems to be a place for it in the town. (the room with the music guy.) HELP!

I managed to become a fish. I met the tall guy and went to the library. I became Nastazie, got the sixth pillar and went back to Humanoid world and ended up by the tree in The Town,. I can now go through every door and got to the Alien at the end of the game. I seem to remember in the IOS version there were Photo Booths where the cats are.

I could see the tree blossom after getting all the pillars, and I can become a fish, but I cannot see any aliens at their corresponding door though. I have tried with many characters. I don´t know what I am missing. Do you have any clue? I am playing the uxn version.
