I just realized there is a Feedback/Feature request forum, so I apologize for the double post in the general forum.
The music in the game is a bit limited, and that is no secret. Has a larger sound track been considered?
One of the best examples I can give is from a music group called Lost Years who also happens to be from Sweden. They make very 80s synthesizer like music. Music like this would sound amazing in the game. Like a different song with different areas/locations. A few rotating battle songs so each battle doesn’t sound the same. Maybe even more sinister sounding music as the level of difficulty increases with the robots, etc.
