As you know, you're certainly at least riding the line. What I generally say is this: If you know for sure that you are 100% familiar with adventure games as a genre, have played lots of them, hang out on adventure game forums and discord servers, etc, possibly made some of them and are just really familiar with the genre, then it is possible to ride the line because you'll know when you've stepped outside the bounds. Otherwise, it's better to stay further inside the lines so as not to accidentally stray outside of them.
