I'm not sure where the questionnaire is, exactly, but i love the game so far!! I'm really happy you used the renpy engine, too since it's easier to understand + all those lovely save slots~!!^^
As for suggested improvements.. It took me a while to realize the FAME stats and FB number of "fans/following" were basically the same thing, so i hope you could tell us about that at some point - like when we first get to open the computer.
There was a scene with Hikaru where our character walks in on him accidentally, and it's just a personal preference, but i really just wanted to leave because of how persistent my character was about the autograph. It just made me not want my own character to do well in the game. I understand it's part of his personality, though, so that's alright~!
I really loved the customization choices at the mall, and i'm very excited to see the rest of the stores! The love interests are actually very charming. You've done great on them! I hope there will be more dialog for the side characters just so it's more fun to look around and talk to others.
Lastly.. I'm still surprised that this is done in Indonesia?? If only i was in Jakarta, i would've loved to help out somehow! I hope the project goes really well for you all. Good luck~!!^^
