Very good start, it was a little hard to get use to the controls. But when I got it down, I found it to be really enjoyable. I would recommend put the scanner on "Tab" rather then "R" though . Other than that great job, Hope to see more.

one bug I saw was Mal0 clipping a little bit into the wall when she is leaning against the wall near the door(not really a bug to me by something to look at.). Another one is when she can spawn behind you. I thing you don't really have to change much for this one besides. Add a sound that alerts the player she is spawning nearby. Like a laugh, sound effect, voice line(if that's ever come to this game.), or a moan. This will give the player time to prepare for her arrival.(but me personal, I think its fine how it is. It's a really good jump scare when it happens.) that all I found, have a good one.
