4000 Seconds to Complete has you completing 5 very different puzzles / tasks in order to unlock the door and finish the map, and you only get 4000 seconds to do so! This concept was inspired by Henzoid's 10^2 map
The task names are as follows:
Rising Lava room
Block placing Puzzle
(sorry the names are vague)
The map is 1.12.2 singleplayer
There is a hint book inside the map that you can use if you need to.
In order for the map in the color maze area to update properly, you will need to set your render distance very high, however it is not needed while completing the maze.
Be sure to post here if you get a fast time!
Finally, if the one area (the color maze) seems very much more complex then everything else, its because it is. It took me by far the longest to make, next time I should try to but equal effort if I do another of these types of maps.
