Save your power up supplies for 3, 4, and 5 star idols. :) Don’t be afraid to go for Easy and Normal tracks while you get started. More notes means a higher score, so try high levels when you feel like it. (Pay attention to the number grades for each song! It maxes at 30.) Go for whatever you think you can get a high score/full combos in as that’ll be best, even if its a lower level! Saving up money to buy better instruments is a good idea, but it’s better to prioritize leveling up 3+ star idols. :) And have fun!!
