Worried about the daily Premium currency income.
So you get 24 Starberries per day and you need 80 to do a limited banner pull. That means you get a single pull in about 4 days. Thats also tied to limited events.
There will probably a monthly pass on launch but that still probably wont amass to a pull in one day.
Theres no real pity in the gacha. You will get something after 10 pulls but that might be a dupe.
Once you visited all islets in the star sea there wont be any starfruit to find, since its not tied to visited islet but tied to found stars.
That seems too little overall imo. Why not make the dailies give 40 starfruit?
