About this Mod
Left Forgotten
Left to fade away into distant memories
Competitor to Alpha Below/The World Below
Based on a tweet by @SlimerSlimy and Minecraft Alpha 1.1.2_01 (the actual version, not the fangame)
Why?
Mainly just to play around with parts of True End's code for soon coming Fabric+Forge port (and because I was bored)
Description
Left Forgotten adds a Alpha-like dimension accessible by blowing a hole in Overworld's bedrock layer wherever there is Brittle Bedrock.
It is dark and abandoned, untouched in years and shadowed by the overworld above with no mobs or anything alive other than some vegetation.
This is not a horror mod, but rather a adventure and decoration mod. Just plain old Minecraft Alpha 1.1.2_01 with a few remnants of player activity from many years ago.

- +A chance to get screwed by music disc 13
Dependencies and Mod Compatibility

Server lagging with Left Forgotten – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Left Forgotten consumes the most tick time.
