Hello,
First of all I want to tell you that I am a fan a rising stats simulation games like Princess Maker serie for examples, I've played others too . That's why it's really with a heavy heart that I am going to give a bitter sweet feedback about the game. Also please excuse me if I sound rude or make typos, english isn't my first language...
First, let me compliment you about the aesthetic aspec of the game, arts are nice, UI is okay and really cool Pixelart but unfortunaly that's all I liked about the game.
The main problem of the game at the moment is that I didn't felt that I was managing anything. I could put under contract my girls, 2 per girls and let the game run in the background then just come back to make them sign a new contract.
Since we're supposed to play their manager, you can either consider to make a scheduling agenda of the girls like when they go train for dancing or vocal or acting.
Here's how they do in Princess maker serie :
The point of letting the player plan herself/himself the schedule of their idol would give them the feeling of responsability and the mental and health stamina will be more meaningfull. Depending of what they make the idol do as work or training.The second option which is closer to your actual gameplay is to give a goal. Since we're supossed to manage an idol group we're normally bound to be prepared for X events where the group will have to appear. This game is similar, it's focused on E-sport team that you raise:
Since you've a wonderfull pixelart artist and artwork artist, it would be nice to ask one of them to do some chibi group animations or drawing. I'm suggesting this because I was disapointed when I ran my Streaming show that I only had stats...Well, that's all. I wish you luck and don't give up but the way the game is at the moment is more a clicker game than a management game for me. Sorry.
