Just finished reading the demo and am loving the story so far Can’t wait for the next update! Btw, I don’t know whether it’s just me, but I still got the infinite loading bug at the end of the demo.
As for the ROs’ sexualities discussion, I agree with the points @Unregistered said. I personally have some friends in the IF community who would always play the same gendered MC in almost every IF they play. I think having set/locked sexualities for the ROs may prevent/discourage some of the readers who prefer to play with a specific gendered MC from playing the other routes, especially when there are no specific reasons story-wise for the decision. In my opinion, the downsides of potentially alienating some of those readers far outweigh the advantages of upholding a sense of realism by having locked sexualities for the ROs.
