The Code is a minecraft puzzle map. In it you need to solve a puzzle to get a code, every solution is in the form of a code. If you rename paper to that code using an anvil, then throw the paper in a hopper, a new room will open. There are 30 puzzles.
It’s got a beautiful look using the new quartz blocks. But you’ll have to look at the video and screenshots to see that.
The quartz is not the only 1.5-piece that’s in this map. It also contains a scoreboard, renamed commandblocks, a light sensor, comparators, trapped chests, visible name tags above mobs, the redstone block, renamed chests, more scoreboards, hoppers and much more.
