I really like this, I think the only thing I would change is maybe the arrows in the top left, they are quite small and really close together, so maybe make them bigger and seperate them out a little perhaps? Other then that keep up the great work.
Edit ... it might be my resolution? My screen is 3840x2160 and I've scaled up the game to 125%
2nd Edit ... no it's deffo too small, changed the scale down and it's still way too small for me personally, attached a screenshot.
3rd Edit ... only way I can get it so that the arrows are bigger is by turning on the text on the side instead of just icons only so I've done that.
