Possible features could include a story summary, character introductions, what's new in the latest version, gameplay features, and a FAQ. They might also want to emphasize the free aspect, maybe mentioning any in-app purchases or monetization tactics. Since it's a free download, maybe they need to stress the ease of access and any promotions or limited-time offers for new players.
Also, considering the mobile platform, maybe highlight compatibility with Android/iOS and any system requirements. User feedback on the game could be important, like ratings or reviews. Mentioning the developer's future plans might be good too, to keep users engaged.
I should also think about the tone. Since it's a drama/comedy with a succubus boss, the tone should be engaging and perhaps a bit playful, matching the genre. Need to check if there are any age restrictions or content warnings they might need to include, especially since dealing with demons or boss-related themes might appeal to a younger or specific audience.
