This datapack changes the overworld generation to flying islands. Survival becomes much more difficult due to the increased number of monsters (including during the daytime). No ore is generated in the world (except for coal and copper)
New structures and biomes appear (classic biomes have also been improved)
Many standard structures have been removed from the generation to complicate the game (villages, mineshafts, etc.) Adventure time achievement changed The nether, the end remained unchanged
This data pack allows you to complete the game and complete all achievement
Datapack is completely stable. There are no critical errors in it P.S. I used Complementary Unbound shaders
