I found a dumb error that makes the trees unable to grow, so the only things you need are a wooden pickaxe and some planks to get to Jerry, on the hub you can chop wood in the forest, later go to the coal mine and obtain stone to sell coal, the coal give you coins. With the coins you can do stuff, after getting a high mining level, go to the gold mine and find Lazy miner's pickaxe, with it you can instantly smelt ores and make iron gear, as starter kit, if you want to make yourself better, make minions, the cobblestone is already made, a good place to fight is the Graveyard where you can fight mobs and make them spawn in your island.
