its more like terraria than minecraft. where you use those potions such as spelunker, mining, shine/night vision potions... and his pickaxe was the Reaver shark(early stage opness)
edit: you can get a weapon which can summons slime from early gameplay, can get a sword which fires magic, or even luckier may get its alternative sword equivalent to crissaegrim of castlevania SOTN... can be raided by goblins and making a houses for npcs(theres a goblin npc as well) that will soon became a village... and you fight bosses, raid dungeons, do fishing and farming, make mob grinder, boss arena anf etc...
