this is similar to the other one that i have where it still decays but has way more interior and upgraded but you can convert it to java with https://chunker.app/ but the entities will get removed and the whole thing was a lots of work and im still working on it if you convert it to java the decaying floor doesn't work to well

the floor decays around you and if you are not careful you will fall into a pit of lava and you can play it with friends if you want or go solo and the java version is available https://www.planetminecraft.com/project/decay-floor/ if you want

both java and bedrock might experience chunk error that gets outo replace with new chunks but its playable

the button that is down below that does not go to media fire is somewhat not chunk broken
