Can you add some in-game text to help guide users what to do. Also I don't know if it is a bug or not, but looks like all the three button move the 'plate' to right. It would be better if you allow to move left as well.
but the game has one button and the gray is the speakers. with each click, the plate moves further. ok I'll add some text
Oh I see. Then I think I was clicking on the speakers.😂
