This is my first Minecraft map, so don't be really hard on me.
There is redstone, but little enough of it, that it will not lag your game.
If you don't spawn in a golden room with the introduction, teleport to -121, 4, 621.
The basic line of the story is that you are a Greek god. You are going through rooms of the 4 basic elements, fire, water, earth and air, whilst battling monsters. The whole map is made of butter, for Sky fans. Also, there is some pretty advanced parkour as you get closer to the end.
If you get stuff like cacti growing, go ahead and trim them to the proper lengths, or if ice had melted, go ahead and replace it, as I have not figured out how to stop that from happening so far.
I spent a lot of time on this, so please enjoy!
