A lot of potential! Already a solid cast of hot characters and an interesting story.
3 Observations/Suggestions:
I think the biggest improvements can be made to the UI. It would be nice to highlight the dialogue more. A lot of times I'm distracted by the background as the textbox is quite transparent and end up missing some of the story. And having an option to hide the textbox for the sex scenes would be amazing.
Also, the mist in the forest is there to make things more atmospheric but it sacrifices a lot of visual clarity, I had a hard time finding my way around and I'm not an RPG greenhorn. Might be beneficial to have an optional tone down.
Battle gameplay wise, unless there's something to hold the player's attention like cool skills animations or strategic planning (attributes/stat points/skill trees, etc), I do feel like it is a waste of time. I think it is fine as is, and I don't think it is fair to expect a innovative and fleshed out battle system for what is essentially a demo for a niche NSFW gay visual novel as I can imagine it would sink a lot of Dev time, so it would be a huge QoL if we can fast-forward or outright skip battles. I think battles are important to make realistic the protagonist's progression, but not at the expense of the player mindlessly clicking basic attack 500 times. Some NSFW RPGs like Lust Odyssey try to placate by having each battle encounter reward the player in a potential NSFW scenario, but they still get complaints on the grind. There doesn't seem to be a good textbook way to implement this.
2 Suggestions (me being nit-picky):
For accessibility, would appreciate if both WASD/Arrow Keys could be used for movement, both Enter/Space could be used for interact/next, and ESC could bring up menu controls at any time (ESC was locked out during certain dialogues, forcing me to lose progress as I couldn't save where I wanted to).
If a quick tap of the movement control could let the character change orientation, without moving. That way, you can "interact" with the environment, sit on benches, lie on beds, etc.
You are right that there is a severe lack of male ASFR games, (and a general lack of non-furry gay NSFW games in the Barasphere). So thank you immensely for creating this. Awesome job! Based on the steamy NSFW scenes afforded by the demo, I'd be more than happy to monetarily support the development of this game. Looking forward to your updates (especially scenes with the detective!)...
