Finally…

Finally reached Ranch Level 20! (*’ω’ﾉﾉﾞ The Wind Dungeon starts getting a bit tougher from the 5th floor. Equipment seems to max out at level 20. Initially, it seems better to refine iron from minerals and level up equipment rather than leveling up companions. For feeding, you purchase food ingredients with diamonds and create them, kind of like alchemy. There are no recipes at all, so it's all trial and error. Once the food is made, feeding it to them grants various buffs like defense and attack power. I have no idea what the different text colors mean though (;´д｀)
