Yeah that caught me quite by surprise as I went along. Spent the first 15-20 minutes carefully sneaking around waiting for anything and everything to jump out at me until it was obvious it wasn't that kind of game.
And I've yet to finish it and I'm not sure if you've played it already and it will show up later, but if you haven't played it then check out Oxenfree Pumpkin. It's ridiculously good so far.
