more details might be helpful.
1. when you played the game.
2. what engine did it use?
3. sb or vn etc
These could be useful in narrowing down feasible solutions.
It depends if there is proper music/sound added. Atm very few games have it which makes the scenes/game more enjoyable. But mostly I have it at very low.
Summer memories on steam, then some other 2dcg games. My first 3dcg was shutup and dance and it got me hooked to avn's, then I slowly expanded to hs games as well.
