A bit short, but fun game. Very interesting core mechanic. Only thing i didn’t like is fact that you can’t apply “nothing” to elevators. But, I guess, it would break puzzle room with go-nothing.
Thank you for feedback :D yes, i had some ideas about "nothing" elevators, but I had so many bugs and limited time, so I must cut that :( original idea, every connectable object has 3 events "nothing", "go", "wrong". But I couldn't make it in time.
