6. Subsurface Circular

Price: £4.79 from Steam (tinyurl.com/ycjscues)

Pairing up well with Tacoma this month, Bithell Games’ Subsurface Circular is another storyfocused experience with a cool, sci-fi aesthetic, but this one is even more compact, and is designed as a single-sitting game. Here, you’ll ride the underground transit system as a robot detective and talk with the other robotic workers, attempting to sort out a mystery that can affect the entire world up top. Sound odd? Maybe, but the visual style is delightful, and the dialogue looks entertaining. That’s no surprise, given that Subsurface Circular comes from the same team behind the wonderful Thomas Was Alone. It looks short and sweet, and Steam user reviews are strongly positive thus far.
