Thanks for spoilering me, I have not finished that game yet ;-b
Please do take everything I say with a grain of salt. I am not a marketing expert, and if a real one told you, you need a new name and a new capsule, there might be valid reasons. On the other hand, just put in some lewd game tags and search for successful games on game sites like steam and gog and look for a common theme in capsule and game name. From my perspective, there is nothing bad about your existing stuff. It even made me put your game on my backlog, even with fear of it being too kinetic.
Pathfinder among many players is a known thing. You know it is a rpg with customizeable character. And you can even create a character looking almost like that demoness or tiefling or what they use as a species name.
As I have not yet played the game I can not give a good opinion, so I based it on the screenshots of the game page. But judging from the other comment, the big evil is nowhere to be seen yet. If Lilith would be better looking and look more ... cinematic, she might do. Look at a Diablo capsule.
But here is the thing. People do usually not stumble about those games by accident, they search for tags or similar games. But even if they do, unlike Itch you can see the tags when hovering over a capsule. So even if you would not know Pathfinder franchise, you would read turn based combat or rpg or something like that. Including gameplay screenshot making clear what type of game it is.
So what would I expect from a capsule of a erotic vn showing mysterious purple demon. I dunno. I am burned child. But if I get the hots for Lilith and cannot woe her, I might be dissapointed.
Here is an exmple of capsule from a game here. It is not bad, but I did not read the description carefully, and accidenntally bought it (it is a kinetic novel and I do not like those very much. I prefer actual game play). What they did bad is the title is not readable in the capsule. What they did good, they promise on the lid quite exactly what is in the tin. The one in the middle is the mc, if that concept can even apply to a kinetic. (And I do not think the title is inherently lewd - unlike the capsule ;-)
The example of pathfinder shows quite good, that you can even have readable subtitles in your capsule.
Pathfinder Wrath of the Righteous Enhanced Edition. Quite a mouthful.
Tainted - a tale of a blade and cups (scnr)
Tainted - Lilith's Revenge
If the mc has no face, you can go Goblinslayer and just show a helmet, when needed. Or a shot from behind.
But I actually like your capsule with the slices of different girls (if that is indeed the story, in other comment it read like there is only mc and a Gewn). It promised diversity in girls, even if I mistook it for a female protagonist game.
