New Bundle and Creator Keys - Bithell Games' Legacy Celebration
Subsurface Circular is the game of the week in our legacy celebration! A two-hour tale takes you underground, where strange disappearances among the robotic working class are coming to light. We shadowdropped Subsurface one day in 2017, but still it found its audience. Its 95% po

We made another narrative short called Quarantine Circular!
Hi all, Did you like Subsurface Circular? Well good news, we just launched a follow up, Quarantine Circular. It’s not a sequel, think of it more as another installment in an anthology. Thanks so much for the support. If you’re seeing this, then that probably means you bought Subs

Update 1 - Resolutions and missed train stops
Hi all. Wow.. just over 24 hours from launch, and I'm so pleased with how this is going. Seems our weird experiment in shorter games is panning out. We just put out an update, here's what it does: No more starting at 768p - Some folks were getting the game loading for the first t
Hi all. Wow.. just over 24 hours from launch, and I'm so pleased with how this is going. Seems our weird experiment in shorter games is panning out. We just put out an update, here's what it does:

No more starting at 768p - Some folks were getting the game loading for the first time at weird, small resolutions. While Unity does seem to have a built in issue here, we've improved the situation by defaulting to 1080p if Unity doesn't detect your resolution. That should make it a bit less of a pain to get things set up as you'd like.
Fix for disembarking/embarking characters - This one was pretty rare, but some of you had a bug where you'd not see characters getting on or off, and would therefore get stuck unless you reloaded your save. We think we caught and fixed this, but do let us know if you have any issues in the pinned dev thread on the forum.
We're still getting a bunch of new folks in, which is exciting, but now's the point where we need to start getting word of mouth going. If you know anyone who you think would like the game, please do let them know! If you liked the game and have a spare couple of minutes, a steam review makes a huge difference too! Thanks for your time, we'll continue to monitor forums and fix stuff as it comes up. Thanks to the time difference here in London, we may not be able to instantly fix stuff, but we hope to be consistent!
