It's a simple game, reminiscent of titles like Elvira or Waxwork if you remember those from the Amiga 500 era. Of course, it makes sense for it to be real-time as the combat is simplistic; it's all about the atmosphere and puzzles. Asking for it to be turn-based is the usual retardation you can see around here, from hypocrites who don't play either genre in any case.
Eh, it is a bit different from that. I understand that people like turn-based over real-time, because in turn-based you can go at your own pace. That said, the game will be in real-time for two reasons:
the games that inspired it were in real-time and it would be easy to abuse a turn-based system to keep moving away from enemies, undermining the danger that comes with encountering them.
Personally I don't mind real-time games, as long as they come with a pause feature of sorts. Exactly because I enjoy playing my games without having to have high APM. I got enough of that experience playing highly competitive Warcraft 3 in multiplayer (and other fast-paced games). If I want to play something action-y, then it won't be a base-building game nor something where you move on cell-to-cell basis.
