"Bad client error occurred" every time i open the game

I have a wired connection and get the same error that Sandsaver01 does. I tried launching it several times and get the same bad client error and it shuts down.

When I push "Play" in Steam I see the "made with Unity" screen, then a popup with "Bad Client Error" appears and after a few seconds the game closes back to Team.

I finished puzzle with 8 steps, but it seemed to be 7 steps.I can not find the SOS button in the solved puzzle. So I am curious about why the AI don't give me the answer directly if I want?

how do i do level make
