Is the game going to be more like a KN, or can the player pick who the different girls end up with?
The game focuses on fleshing out distinct endings rather than allowing multiple choices for girl relationships. There is a possibility of an ending where Ruru submits to the MC in a dominant/submissive dynamic.
How do I solve the 'match by look' issue in the game?
The source does not provide specific steps or solutions for solving the 'match by look' issue. Further details are needed from developers or community discussions.
Will there be a futa on male scene in any of the endings?
There is a possibility of including a futa on male scene in one of the endings, but it would only occur towards the very end of the game and depends on the MC's dominant/submissive dynamic with Ruru.
Is Ruru the only futa character?
Yes, Ruru is the only futa character in the game.
