I agree slow burn ntr is the only way it should supposed to be the most important things that no or almost no ntr game gets right are
First Point realationship build up:
A realationship build up like our red string with ian/holly or ian/cindy or where it all began rework miru/mc or summer is gone bella/mc are good examples for relationship build ups that you actually care for the love interest and have a connection.
Second point writting:
a game that is on the same level like our red string from a writting and realism point no stupid mc or plot holes or unrealistic fast sex.
Third point antaronist:
A Rival that actually has a personalitie not just a blanked that is just the bully or just evil without any personalitie.
Fourth point slow burn ntr:
The love interest should care about MC and have a strong connection so the corruption should be logical no (mindcontrol or any weird stuff) just a struggle and how she slowly lose control.
and many more ......
sadly most ntr games are very bad
99% probably in my opinion because they have huge problems with logic,building a conecction between mc and love interest, or she falls to fast for the antagronist and so on....
hope the dev is alright and continues in the future
