What a cool game! I have not played a game like this before. After trying it out, I have the feeling that after some time, I could get a good grasp on the mechanics and in game economy and start doing well.
I am writing because I do freelance game audio - music, sound design, implementation. I would love an opportunity to help you shape the audio half of the experience of Project Ironhaul. I can already hear the clanking of the wheels on the track and the sound of the engines in my mind's ear! If you're ready to start thinking about the audio aesthetic you want, hit me up anytime; I'd love to chat about it :)
Either way, cool game! Keep up the great work!
