I kinda fixed my map system and now there's bedrock (actually it's obsidian

) at the bottom.

And that also means pretty night sky and grass

I see you're using a Minecraft texture pack....I just don't remember what it's called.....but I've been waiting for someone to port this and yay! I might be able to help with your level generator.
I used
this texture packI'm open to help for level generation... I don't really know what would be the best way to generate

That looks awesome! I used to play Motherload all the time
Edit: will this be open-source?
I suppose so. I'm gonna make the code a bit more pretty first, though
