Instead of finding buttons, how about levers?
There is 15+ minutes of gameplay packed into this map, coming from the amount of research it took me to actually get command block codes, I think it turned out really well.
I have tested out this map 17 times, and trust me it was annoying, but I have fixed *I think* everything and it is now playable!
I put a lot of effort into this since it is my first map that I have made! Hopefully you guys will enjoy!
I will upload a walkthrough of my map asap!
*please report any bugs!*
