Please be aware this is a very easy level. I was not able to figure out how to take what I saw in my mind's eye and bring it into the game. I would love any advice or feedback that tells me how I could increase the difficulty, while making few changes to the form. Even though it is not a hard level, I think you will agree it is very visually appealing, as well as an interesting concept.
Great architecture and locking mechanism. My only suggestion would be to scale down the size of the gate and put the locking mechanisms on sliders without draggables that B has to release in some other way (pushing levers, dropping balls etc.)
