Steam review snapshots
It's a fantastic narrative game where you play as a robot detective solving a mystery in a futuristic subway system.If you’re into story-driven games with a solid mystery and some philosophical depth, definitely give this one a go.The writing is sharp, and the world-building is surprisingly deep for such a short game.It feels like the author did want to point out those parallels, but then didn't have the guts to actually explore them.Why it fits
Check it if you want adventure, casual filtered by relaxing, single-player.
