It's Whisperer by GuroGameGuy. I played it like two-three months ago and I can't say I remember a whole lot about it, but it was pretty easy to beat; probably took around 2-3 hours.
This is really well put together. Most games that boast some kind of violence are either very over the top or non definitive about the amount of violence (imo). This on the other hand is well done, the animation is consistent, and the sound design is good. Keep up the good work.
