I don't think the indie industry is about making simple games. You will be accepted in the industry one way or another. I do think you should hire someone, it will make you happy and that's simply what game development is about. Also, if you want me to do the song for free I can, but it probably won't be that good and will probably take me a while.

I appreciate the thoughts.
I think I'll hold the thought on who to do the song, on "standby" for a bit, until I figure more out.
But I do appreciate the offer.
It might still end up that I need your help in the future with something, though. Because your programming knowledge is really good. (Nothing specific I need help with right now, but the way things go... there will probably be a time where I'm asking people for help on Unity.)
