Thank you, glad you had fun^^
Yeah I think colour coding the different buttons would make things a lot clearer, or maybe have a line that goes from the button to the blocks they affect, like in portal. I didn't think of that, because I placed the buttons and walls, so I knew what each button does. Only when I saw other people being confused while playing the game I realized that they have no way of knowing what a button does, until they press it lol.
