To note on Nebel's developer, BBQ Daisuki / BBQ大好き@LiuhunAZ (X handler):
He is still in NTR market. The short game release was due to the fact he got 'upset' with himself for not releasing a game last year (a year of hiatus to move from CN to JP).
What he has deep-delved into is NTR FPS.
Here's a pre-Alpha of the game and website:

(it is google drive and nothing much of H in it, just technical test)
and here is somewhat planned NTR serving of the game:

There was a non-public/verified response by BBQ that he will not make the NTR scene deliverance similar to Nebel (random generation based on hidden stats) as there were a lot of feedback disliking it.
Now I use he because it would seem he's working on things alone but I am unable to get concrete proof of otherwise. But I think he is quite player-eccentric developer as he does 'spam post' for feedback/reviews on X. Now don't go demand on his X on Nebula

simply wait and see then vote with wallet (if you can).
