All in all, I liked the map and it shows initiative. However, there are a few bugs, and while I understand it is in Alpha they are game breaking. The NBT tags that make the item only be placed on a certain block (emerald blocks) don't always work, and for me just didn't work at all in some levels. This meant I could literally put a redstone torch and repeater next to the gold block to complete the level :/

The final level is passable by placing the redstone lock inbetween the repeaters, by the way!

Please pm me when this is finished, I'd love to see the final product!
