If this game is ‘short’, what’s to stop me getting a refund when I’m done?
You’re browsing Steam, which means you understand the work that goes into games, and are in principle up for paying for ones that entertain you. We hope that after a bit of time with Subsurface Circular, you’ll feel good about the price you paid.
Why is the game only available in English?
As you can imagine, a text adventure game contains a terrifying amount of text, but more importantly, throughout the game we use the particular quirks of word ordering and double meaning in English to support the combination and recombination of threads. Put simply, other languages are going to be more than a straight translation: They’re going to need rewrites and changed design. Not impossible, but more than we could get done this time around.
