I found it somewhat interesting. I like the characters, the art, and the soundtrack. The design is very charming.
From what I've gathered from one blind playthrough and two fast-forwarded playthroughs where I chose different options, Cryptid Crush is a kinetic novel with just a faint fragrance of dating elements. You're given choices, but as far as I've seen, there isn't anything that has a significant impact on the story. Choosing a different option maybe gets you a new crumb of world building, but ultimately just leads to the same places.
In the existing content, character interaction also feels very heavily skewed towards Madhouse and August. Madhouse is attached to your phone so he's in almost every scene chiming in, and there's quite a lot of 1 on 1 scenes with him even if you completely ignore every interaction with him. August is the only one that you're given the explicit option to flirt with, and similarly, if you ignore every interaction with him you'll still get shoved into the same 1 on 1 scenes with him regardless. Neither really goes anywhere in the existing content.
For everyone else there's a few scenes of either meetings or friendly hangouts that are quick and shallow. One such meeting in Chapter 1 with Jamie at their day job just has a rough line-art placeholder still despite chapter 2 being released and chapter 1 having been out for almost three years. After the first run it's very apparent that attention has not been equally distributed between the characters.
-----------
Based on the past release frequency, unless the next two chapters really go hard on the dating elements it's probably going to be another 3-4 years minimum before there's any substance to this game as a dating sim.
