This looks amazing! Looking forward to updates.
Curious as to what the music is going to be like. Do you have anybody doing the score?
Currently no. I write a lot of music in my spare time but I'm not sure if I'd use my own for this. I'm thinking of going around ambient synth stuff and synth rock stuff. Also been listening to a ton of Com Truise during development and that's definitely a huge influence since it really fits the aesthetic of vintage vector graphics with modern advancement.
I might contact some people eventually but this game definitely will have a soundtrack, even though technically speaking the game itself also uses audio channels to run. Luckily, unity allows for multiple channels, so as long as I don't need anything beyond 5.1 channel audio next to the graphics audio feed, things should go real smooth.
