As i promised, i started working on the nether!

Added some basic biomes and stuff. not that crazy

the crazy thing i did here though is LIGHT. Now the server properly does lighting! Blocks that do light, now actually do light! Now, its not perfect. for the sake of performance and keeping that 7mb memory usage low i had to make some sacrifices. the light is per chunk, so if you place a light source between 2 chunks, you will see seams.
But it wasnt all smooth sailing sadly :(
most of the time i spent was fixing a segmentation fault caused by musl. It took me so long. It wasnt happening when just compiling with the system compiler, musl specifically was causing it. Every time a user joined the server id get a seg fault. Turns out, it was just a memory allocation bug. Since i have to be so tight about memory, it does cause issues as i said in my previous dev logs. Well anywayyyyyy! Next thing is gonna be nether mobs and structures! Maybe even trading?!?! no idea we will see if i feel like it lmao
