You are right:)
However, I am working rather on a simple 2d game based on old idea. Player is flying a space plane and dropping bombs on enemy units and facilities. There are also enemy fighters which player have to avoid and may destroy them by firing missiles.
Hope, soon I will be ready to share a short movie.
Going back to your game. Music is great:). What is the software you are using?
You can also add some sound effects, for example when you hit something or when player is near monsters can hear their snarl.
I’ve postponed music and sfx dev for now. Maybe I will find someone who will do it for me or find some assets
I still have a long way
