You know, I believe this game struggled in the past because, during the early 2000s, the gaming landscape was largely dominated by a more masculine audience. Even titles that once featured female protagonists, like Resident Evil, shifted away from them due to the perception that people wouldn't embrace games with female leads, partly influenced by the underperformance of games like Beyond Good and Evil.
Additionally, I hold the opinion that the color green wasn't particularly marketable. Growing up, I watched Precure, and it seemed to me that the green Precure toys were consistently among the least popular. Therefore, from my standpoint, green carried an aura of bad luck in terms of sales.
