Every time a dev of an unfinished game says that he's working on a big overhaul, I get scared.
Oftentimes, it's either an overhaul that doesn't really matter but still takes a lot of time and resources to implement, thus becoming a waste, or it's a straight-up downgrade because the dev suddenly decided that he wants something to be different, like what happened to Saria Reclaimed.
I pray that this game's "overhaul" ends up being more-or-less okay, though I'm almost completely sure that I shouldn't expect any new sex content, considering how slow the progress was when the dev wasn't working on any "overhauls".
