The game was finished a long time ago and I've moved on to another projects, so it's not going to be updated any time soon I'm afraid. Still, I appreciate your enthusiasm!
It would go against one of the core tenets of the game, which is, there are no living creatures to interact with or observe other than the single plant. Furthermore, having an easy refill of sanity would throw balance out of whack, since a lot of stuff hangs on the fact that sanity is hard to recover and easy to lose.
