HoloCure is a fun game and at the time of writing  i played at-least 20 hours, during which my time spent; be it by doing runs for farming Holo-Coins for the in game shop,
Purchasing either Global upgrades  or  Praying to, 'RNGUS'; (RNG + JESUS), to upgrade the V-Tubers that I either main, (ones I currently do runs with) never seems to be pointless Endevours as it helps you purchase more upgrades either Global ones  or single Upgrade/Unlock vie RNG  Based Gatcha Banners..

Pulling from the gatcha banners grantees to either help you upgrade your V-Tubers  or unlock new ones, once per Purchase (Costs 1000 - HoloCoin - In game Currency)

If the Idol is currently unlocked or been previously ungraded allowing them their Upgrade Level to be increased by 1 - Up to 20 times after that specific V-Tubers initial unlock.

It defintely helps that the V-Tubers are separated into small Groups (Banners)[RNG Still applies but is limited to the choices avalible within the related Banner's [Idol Group] Pool.

Increase likely hood to be able to get the gatcha you want and making it easier to upgrade Idols and get new ones in that banner...
It also allows players to whale on banners:

[Select V-Tuber Banner == Limits your potential choices]

<Debut>

[1st time Idol] = related Idol is Unlocked for Runs]
OR - [Duplicate Idol  = +1% base stats upgrade for Related Idol]

Return to menu...

I have one-to-two problems/Bugs; neither for them are game-breaking,or run-ending; maybe run-forgetting or something like that...

Those bug that i have encountered and keep encountering are noted below: But take be descriptions with a pitch of salt. as I am unsure if the features are either implemented or failing to start-up-right, or its my machinealthough it an High-End-Gaming-PC -With Powerful Multi-Core CPUs and High End GPU including a High-Preformance Graphics Card)] is preventing connection to your High-score server for some strange reason,
I say this because:

I've been unable to upload any High-Scores from any endless run nor been able look at the leader-boards online from in game during any game-play sessions regardless of search creitera, Is that intentional for now or have I got a  server Connection Problem...

Note that since I don't know if its not been fully Implemented yet, Are the different Songs avalible in game or not?

This is due to me hearing the exact same song, each run, each time, each game, each session, don't know the song title, but I positivily sure it the same song right down to the melody and beets...

are any of these problems related  to the  game's currently normal behaviours or is something going wrong my end or inside the game itself? 

Please Help ... Doesn't need immediant attention, as and when you can fix those bugs and features:

I am really looking forward to the new wave of Idols and Controller support, cannot wait to see how this pans out and Progresses, I been very Fun and I hope to continue playing and enjoy my time spent without having any regrets... Haven't had any regrets whist playing HoloCure,  bar one regret being that; I just wished that I could continously keep playing it, but I have to Juggle both my life and wellbeing and my gaming obssesion reasonably and also balance play other games that i enjoy paying aswell   

You Doing Well And Keep it up, this game going to go far, Well Done, And Best Wishes and Even more Blessings That you keep working on this fine Fan Game of the Holo-Live Génré, But don't burn yourselves out either nor Forget about yourselves or your personal IRL surroundings and your various IRL/Online Social Circles/Studies/Groups/relations, as If you were not here, would this game ever be made and Would we the [Fans/Players&Steamers] have have the many various Delightful moments gained due to playing this game either alone or with friends or streaming it live with Fans...

The Answer is : DEFINITIVELY NOT,
You have made an Great impact on the world, but the world need to be able to relax and enjoy itself as well:
You are important, the game is secondary in importance to you as, No You, No Game, No Impact: ----> NO HOLOCURE or Development Limbo.

Goodbye, GoodLook and Keep looking Forward, Both in life and Virtual-Space:
