A 1.16+ map about searching and connecting the dots. Each room based off of a specific idea or theme the map i quite challenging.
This map can be played singleplayer or multiplayer. It is created for singleplayer but should work fine if you teleport the second player inside.
This map should be played with your Brightness level to the max as it is then the easiest to navigate. You can play it with shaders but they may make some rooms darker then they should be.
If you are truly stuck there is a hint book you can locate early on in the map. The last Item is very hard to find so you may want to rely on the hints then.
