I would personally watch a no spoilers tutorial on YT as you go. Also as a heads up. The robot is busted as fuck. Op even. Use the robot. Upgrade the robot. Look up YT tutorials on how to upgrade the robot if necessary. Playing a mini game is required to do this and you WILL spend hours of your life on the same mini game over and over. Trust me. The robot is that good.
except once you get to ng+. then you only need to play the minigame for one affinity node, but everything else can be bought from the new vendors using unused bonus exp.
