This game goes back to the arcade Im@s roots. It is a really simplfied version of that and it isn't that bad. The biggest missing thing is the lack of 3D models, meaning no dancing MV, Idolm@ster series main selling point.
Also, this is the type you don't need to play everyday. Just a few Produce a week and some FES and you can get the main event rewards easily. But if you play a lot, you will feel burned by playing the same events over and over.
Overall, a nice game for Im@s fans, just to fill the time when you are recovering your stamina in other games.
The audition's turn meter in the app was laggy af, unlike the browser version. Also, the content movement was a little slower compared to the browser version, which was smooth as hell.
Still, definitely try the game if:
You like idol waifus
You like complicated gameplay
You love the Idolm@ster franchise and wants to relive the good old days of the arcade version of the game
You like RNG heavy games (because man, this game has a lot of RNG)
This is basically a simulation of how to produce an idol somewhere close to that, even communication with the idol is important like keeping their confidence up or keeping your promise with them when they make request. The game gets really complicated especially for people who can't read japanese. The graphics is amazing the way they use the live 2D system I really like it. It's not a rythm game guys it's an idol simulation game.
