Thank a lot for review. I am happy you liked it :D
There are few things affected by the address. One symbol changes the ground color, one changes type of rocks and vegetation as well as their color, one sets the conditions, two other affect the spawners, slime color and rate in wich they spawn. The rest basically changes difficulty of enemies and chests loot. So every time you visit the same address it will have the same difficulty/look.
Thanks for the sound reminder. I will look at it.
