I can't skip, can't play a chip, can't move, I do not understand what is happening. The clue in the walkthrough is useless because I can not place a chip

... so I cannot proceed to the next room as it is still locked. I believe I finished "level" 71 (or maybe 72?)

Doesn't look like anybody on Steam completed this game...

I believe this is called "Connection of Worlds: Mirrored Earths" elsewhere; just like: Crossroad of Worlds: 100 Doors (aka "The Intersection of Worlds: 100 Doors" elsewhere) Crossroad of Worlds: Mystery Agency (aka "Secrets of Worlds: Mystery Agency" elsewhere) This is something that should be prohibited....
