Hello Lyon, thank you for commenting on my project! The block "falling from the sky" may seem like they are falling, but they are just chunks that have not been loaded yet lol. And for some reason the order of loading makes so it looks like they are falling form the sky :O
What ideas did you have in mind, about expanding on the "block falling chunk gen". Cause when now I think about it, it sounds really fun.
And yeah, Happy New Year!
