The first time I played this puzzle was on May 17th, as I mentioned in my previous message. I pulled down both levers on the sides, but the door didn't open. About 5 days ago, on May 29th, I played the puzzle again, and the same thing happened. So my partner and I took turns pulling the two levers up and down, one on the left and one on the right, repeatedly, and then the door opened. I hope that my description of my situation can help you identify the problem.

I don't understand why some people can't.
Changed the door to something else.
I hope this fixes it.

Already achieved both levers but the door at the exit did not open. sad:(

I didn't end up in the same situation.
So I changed the button to a lever.
I think you could probably fix it.

Same here. The red button didn't work. The rest was good

at the end of the level where you hit the red button and the blue button to finish the game the red button does not light up for the end doors to open so we can not finish the level. other then that me and my 5 year old enjoyed the level. please fix so we can finish thank you.
