It looks good, it does give off an old flash game vibe at its current state!
I would say that in my opinion it feels very cluttered, I assume it's supposed to be the Main Menu and a Character Selection? By the Discord, Twitter and Steam icons?
Separating those into a separate screen could lower the clutter.
If you look into XCOM 2 and Papers Please, you would see that the UI elements often feel immersive (Although the only immersive thing about XCOM 2 UI I remember is the loading screen).
I would also say that when I look at it my eyes are immediately dawn towards two elements, The Big Screen (Team Comm) and The Three computers on the bottom.
Apart from that, I wish you luck 😁
