I thought this game was quite good. I can’t really speak to the themes, as they are not things I have experienced personally.
I’m very curious about the decisions behind the artstyle; it’s not a look I think I’ve ever seen in a game. Very disarming and uneasy.
Just after I posted this, I had a thought: I think the genre of this game is interesting because… nothing about it comes off as speculative fiction, technically speaking. It doesn’t linger in the realm of magic or sci-fi. However, by form, it becomes a kind of magical realist story. Venturing through a tunnel through the back wall of Ally’s shower through time functions as a less abrupt time jump. But by making that journey, one in which you travel by foot, it makes Curtain exist on a boundary of realism, where time and space are decoupled and recoupled in strange ways. Which is kind of cool to think about.
