SuperDark mode

I get how people complained how too dark Minecraft's nights are. For a balance, Add in a toggle in the world settings so if SuperDark is on, All natural lights for darkness should be highly dimmed, up to pitch black in overworld dark zones, 90% dimmed for natural night light in overworld, 80% dimmed in the End, and 70% dimmed in the Nether. All light blocks will never be effected by the settings. If it's off, all dark areas mentioned shall be as bright as current Minecraft.

If you want this darkness as a challenge AND as a toggle for the world settings, vote for this post.
