Hey thank you for playing and I'm glad you liked the atmosphere!
The controller issue is something my colleague discovered when I was making the last update for Terminus. I don't have a controller (but I plan on getting one soon hopefully) but a friend told me that Start/Select do not work.
The reason is: the plugin we use for controllers had an update, and that update somehow broke Start/Select detection. Since I couldn't properly test it, for Terminus I reverted back to the old version of the plugin. When I get myself a controller, I'll try to fix it. (because right now doing it blindly will be too time consuming)
Yeah, some camera angles do have areas where you can get out of the screen but it should lead you to another camera angle eventually. The one problematic one I can think of is the one near a pushable box. If there's a box in the way, you'll get stuck on it without knowing because the camera angle wouldn't switch. If that's the one you're talking about, I'll try to fix it if there'll be an update.
Hmmm did you pause or go into menus often? Timers should stop when you're inside the main menu, maps or pickup screens. As for not getting discovered: the eye-icon needs to turn red in order to count that as being discovered (and you also probably need to be in enemy view, not sure) so if you've never gotten to the point of aggro-ing the enemy fully, then the game doesn't consider that as being discovered. :)
Thank you and no worries, the 2nd unlockable is daytime mode (where the entire game is lit and you don't have the lamp in your inventory). I'm glad you liked it despite some bugs and issues. :D
