The game's style looks like this, this game is Highschool Romance and is NOT the game I'M looking for, but the game I'm looking for has a very similar style.
The creator's name was daishnko or danishko or something like that. I sadly can't remember thus can't find the games.
In one of his games you were a female detective you would get stuck in a wall etc, as said above, the art style was ultra similar.
In the other you would choose between 3 female protagonist and each would have their own path, stories.
With one as far as I can remember, you worked with a magician etc.
In the last game you would again choose between girls with red, green, purple, blue hair, and each would again their own paths, stories.
Please feel free to help or add any information if you can, much appreciated.
Edit : I think the creator's name might be starting with an "N" as well but I'M not sure.
