This is Terrain Generator 2! It was made in June of 2024. (NOT NEW.) My newer projects are better, but I have not shared them yet for reasons. (They're coming very soon!) Click the green flag and watch! Mess with the height change slider to mix things up. Flowers and grass now exist!
Blocks are from Paper Minecraft and originate from Minecraft. Height change 0 = flat land. Mess with the slider during generation for weird results...
