The 'traits' evolve both with what she do/happen to her and what she think, not just with choices, I wanted the evolution of the 'traits' to feel not as just choices from the player, but as the character itself evolving and changing.
Though the thing is that Myriam was written to enjoy cum, the 'trait' was mostly here for players that want some extra more, changing it down manually will not erase it for the game as the game was never written to make it disappear from the start, sorry.
About the 'cum' kink, nothing much to say beside it won't go away for sure, at least not for Project Myriam, two of the biggest kinks that frustrated me in games I played before was the lack of 'anal' and the 'one second small cumshots' that disappeared on the next render, and instead of pestering the devs I chose to try myself at making one (this is not a shot at anyone here, but just a comment on my thought process at the moment I started Project Myriam).
So definitely, the over saturation of cumshots and anal is definitely due to my enjoyment of it, and it's totally fair if you prefer to stop the game if you don't enjoy it, there is no reason for anybody to force themselves playing a game with things they don't like.
I hope you can find the perfect game for you out there (there's a lot of them after all), our even try yourself to make your own like I did, meanwhile I thank you for all the time you gave Project Myriam. ^^
