I typically play games without critiquing too much during gameplay. I want to focus on having fun and taking in the game as it unfolds, then give a quick review and critique in the outro of the video. However, I couldn't help myself but critique and review as I played because there were so many things to comment on as far as improvements were concerned. It'd be too much for me to go over them here in the comment section, so I urge the developer to watch my gameplay and take notes.
One thing worth noting here though is the size of the house. For a couple who just moved in and planning on starting a family, a huge house is pretty unbelievable. I know it's an indie game and that delving deep into the story isn't necessary, but for a story seemingly grounded in reality, it's difficult to take the game seriously because of the mere fact of the location of the game: a mansion. Granted, the demo doesn't show us the size of the house, but all the rooms we come across (some we can't even access) give us a good idea of how big the house is. It doesn't make sense for a couple who's planning on starting a family to be moving into a house of that size.
Ravings can be an enjoyable walking simulator for what the developer is able to offer. Personally, the developer didn't offer enough. From what I can tell, the game is about the ravings of a man progressively going mad manifesting themselves as hallucinations. It would've been a better demo if it delved into why he's experiencing hallucinations, why he and his wife moved into such a huge house, and the story behind the house. I feel like there's something insidious about the house that's giving the protagonist hallucinations. If so, why wasn't the wife affected before she abandoned him?
As I mentioned, there's a lot of improvement, but nonetheless worth checking out.
