Hmm I tried some sort of experiments in my comic like, making the episode more enjoyable and funny, with a couple jokes, some pretty silly ones and others more elaborated, because the pacing is very slow, since it's a mystery genre
The last episode, which has more elaborated jokes with movie references got more engagement than any other episode so far. But it also takes time to make one episode like this 
I've never done a survey, but I can feel what my readers think about the comic when they take their time to comment and leave a like, if they don't, maybe there is nothing to say about it
