It's about the development time. If this game was made at DrPinkCake or NLT Media's speed, the vast majority of the comments would be like yours.
There is a huge difference of development time between Being a Dik and NLT's games, obviously BaDIK needs no explanation. Whereas, if you're looking for a in-depth story in NLT games, or at least the newest one, you will find nothing lol, it's really great sex quality for very little time, but story wise it's a cluster fuck.
Lastly, when you say "Besides, the dev here tries to justify a 5% or 10% better render quality than those devs, with more than 300% in development time." I agree 100%.
