I don't think we will have pregnancy during the game itself but at the end instead, when we describe the fate of each companion and characters depending on your actions during the game. So there might be a few wholesome scenes but don't expect something too significant.
We wont have an early access on Steam because Patreon is enough to finance the game and we want to release a finished and polished version on Steam. It gives us a clear goal to end this game.
