This AVN has been a bit all over the place and I hope the developer settles down on a route now. Fact is that several side characters seem to be optional but there are main LIs that will not be. I am also disappointed that the Queen gets killed, though we don't officially see her die, she was stabbed in the gut and could survive, perhaps that is also the way to absolution for Alex? Personally I feel the 2 options to either slap her or forgive her were not great. Sure slapping her could work, but simply forgiving her after she killed one of the MCs LIs? I am sorry but is the MC that fickle? Did the queen not mean more to the MC? Do we accept regicide like that?
I think the developer is juggling too much and not sticking to defined script but being reactive or something. The idea I mentioned above can work, the dev can keep the queen alive as a prisoner (a bargaining chip) one that could even throw a spanner in the works for the MCs plan to seek help at the other king, who had a thing for the old queen. I also believe that the MC can eventually catch Avery and get her to submit to him, make her a breeding sow after her part in the plot is revealed. Unite with Rebecca and then take over and set about to attack Alex's dad(whathisname) and save the old queen. Obviously some side stories and details can change, but this idea could work, but killing the old queen off is not a good idea...
I have some other ideas also for the developer if they keen to hear them, but this was the crux of it.
