I think the #ZAGS planner feature (which has a bunch of unlockable actions and which also can trigger VN sequences with additional scenes and story) is my favorite VN thing I've ever coded up
The more game-y thing I'm the most proud of coding (and designing!) is the snowballing door puzzles in Over The Moon, with a close second being the RPG engine used in Orcs of Mordick and #ZRWP
But the games I've made that people seem to enjoy the most are the strictly (and straightforwardly) visual novel ones, like YAGS or At First Sight or Charles 2.0, to the point where it seems there's an inverse relationship between how much the programmer in me enjoys a project and how much my players do
Trying to consider what this means for my 2024 #GameDev plans (including my continued desire to pick up an engine other than #RenPy )
...and particularly for a specific project where I've started commissioning art >_>
