It has tensionless scenario, mere formality netorare, convenience-oriented stitched up, first-person protagonist with only bad ends...everything you can find for a mediocre fap game. The only charming point is the voice actor and dialogue design. I mean, she really is making this sounds miserable.

So, by all means I'll recommend tsurumiku. At least they do produce stories rather than toilet paper

Backgrounds are quite good. Always liked artstyle of those which Lilith had.
