Honestly, the math took me a few hours. I pretty much spent 5 minutes on everything else. This was mostly me learning to use AS so I could make a real game later. Thought I should share it for the lulz.
Left handed guitars also have strum/gaurd plate reversed, so you don't scratch up your guitar with the pick. And even if there weren't left handed guitars, why would that exclude them from a simulator? A simulator should have MORE options than IRL.
