I am trying to do "the eight puzzle" which on pc mouse/keyboard is different from gamepad version. when arranging statues in correct order nothing is happening. can anybody help?

Have you tried checking out where you are stuck in the full PC video walkthrough of the game here?

that walkthrough was just the job, I had searched for quite a time but couldn't find a walkthrough for that version of the game. thank you

You are most welcome! Have fun with the rest of the game.
