This is too short for a demo on Itch. That said, it has great potential and I love the art style. My biggest recommendation is a Skip button to bypass encounters we've already beaten before.
And if you want to speed up dev time, don't do sex scenes for mobs until the rest of the game is done. The time spent on the art and dialogue for those is better served making new npc avatars and writing the story. You already made win/defeat summaries anyway.
Something like this:
1. Static NPC/Mob art + dialogue. Includes win/defeat summaries, in-battle art, and rest/relief art, for common mobs and bosses. Equipment. General combat code. Core story.
2. Primary routes for story, ie main route + close-branched routes. Equipment wardrobe expansion. Sex scenes.
3. Uncommon/rare mobs (like whip enemy). Alternate routes. Static general art more expressive/animated. NG+. Complex combat code.
4. Story+. Community voted/bought content. More platforms.
That's the most efficient way to develop games, especially H games, because the more content you have sooner the more donations and feedback you'll get. Don't overload your plate trying to have 5 scenes per mob right out of the gate.
