Thank you very much for the detailed post. Glad to hear you liked the early game missions and setup. I wonder if you have reached Haven yet?
With the sister, it is planned for her to be an integral part during the first weeks and post Haven. But I haven't managed to add her in properly yet so right now she just ends up vanishing. Will be a lot of early content with her though where he helps you adjust/adapt to the new life and body.
Pregnancy will be avoidable at some point soon, just need to get round to adding it in.
Customisation from the start is something I debated, but kind of wanted to get the player into the action as quickly as possible and not spend ages deciding what type of character to make when the game hasn't even started yet. I may revisit this decision though at a later point.
And yes, supposed to be roomies but still need to actually add them.
