That's very vague. Is there anything else you remember?
1. Was it a Ren'py game? - It's very common, especially if it's Visual Novel. The easiest ways to recognize it is that Main Menu is very characteristic, as it commonly uses the same font and has similar options. There's also a text box on the bottom with a couple of options in the middle. Here is an example:
2. Another very common game engine is RPGM. It's games almost always have a bird's eye view on the characters and the gameplay is pixelated. Does something like this ring a bell?
3. I assume the Main Character is a male, right?
So we can assume tags like:
male protagonist, fantasy and corruption from what you said.
4. If the hero ends up corrupted by (I assume) the demon's daughter, was it a
Female Domination type of game?
5. Can you remember any other girls besides Demon's Daughter that MC could romance with?
6. Lastly. Roughly how long ago did you played it? Was it a month, maybe a year ago?
