Aty ranks among the best visual designs for a FeMC ever made. There's a reason she has endured as well as she has, even getting a few cameos in the publisher's other titles.
Not even that implausible to work. A decent number of PSP games have been ported to PC over the years (the system already enforced having sane, non-properitary, text handling and a near 16:9 ratio), and as a prequel the game doesn't run into the story issues starting from the third game would normally have.
