Hi! Thank you for your feedback!
Yeah, I was a bit lazy when I implemented that part of the control system :) (funnily enough, I'm also a lefty but I prefer wsad), as you say a fix shouldn't be too difficult, which makes it all the more frustrating that - because this is a university project - I can't touch it until my grade is finalised (which is either a few months from now or a year and a half haha). But I will definitely remember alternative control systems for my future projects :).
