It's an interesting interpretation, showing dementia's awful progression and finality. It really is a nightmare that's hard to conceive.

Kind of painful to play at times with the lights flickering so often. I get this isn't supposed to be "fun", per se, but that doesn't mean it has to be quite so violent on the eyes.
I really liked the ending, I learned a new, very interesting thing about dementia and this utilizes the medium very well to show it. Great stuff.

Less a "game" and more an interactive short film, I'd say. It's hard to rate it, but overall I think I somewhat enjoyed what was offered here.
If you've got GZDoom ready to go, try it out, but if not? Probably not worth the download (unlike My House, which definitely is).
