I have started work on a second game already but it's still a long way from being done as it is much more abitious than Last Hope. I also don't want to stop development of this game yet as it doesn't have an actual ending and there are still a lot of scenes I want to add before moving over fully to the next project
Do you plan to eventually transform some of the LH scenes to better reflect the current situation? In other games, where there is progression you can still trigger scenes that make no sense and have dialogue from much earlier in the game. Things like spying on the mom/captain changing in the morning should have more options after you're freely having sex with her, and not doing the same old choices from earlier on.
I'll second what others have mentioned that the last update, focusing on the aliens, was a bit bland. Frankly it seemed shoved into the story just to add a new female character and some BDSM elements. It would seem to make more sense to expand on the already existing relationships with the other characters, like surely they'd all notice the 'tension' on the ship now and how the women's interactions have changed with the MC.
IRL it's fairly obvious to tell when people have started having sex, unless they are specifically trying to hide it, and I would bet with all of them being horny all the time, they aren't really trying to hide much at this point. This would naturally lead to some revelations and discussions among the existing crew and more opportunities I think.
That would, to me at least, be a much more interesting direction to go than what we've seen with the aliens so far.
