I second this! I think it'll be a really good idea to have a discord platform. Using discord might be an easier way to report updates, bugs, provide feedback and provides a community for us players to hype and share our experiences. Most beta games I'm participating in atm seem to have a discord so, I was wondering why Idol Manager didn't have one. :-)
Am really enjoying the game so far and I'm so excited for the next update! As what others here have mentioned, I think the relationship and event system is one of things we can't wait to have improved. I'd be holding off playing Idol Manager until the female manager update and now I think I'll give it a break until the next one (so my idols don't graduate before I get a chance to bond with them, haha). I strongly feel that more personalisation/life/variation should be implemented to the idols as it would really improve the role-playing aspect of the game. More types of rooms/staff, and a tutorial would be nice as well! There are a couple of bugs I've noticed (time freezes until relaunch, idol avatar not being the same) but I think a great job is being done so far. I really like the trait aspect and the shiny cards.
Keep it up devs! Thanks for taking us on this journey with you - we can't wait to see what you have in store for us next :-)
