Glad you enjoyed it! A sequel was planned for Broken Silence a while back (some concept material was even shared in a patreon post) but it was ultimately put on hold. Making a game with the same quality of art/music/voice acting as Broken Silence is something we currently can't afford.
However, we are currently working on a visual novel. It's a bit different (in style, tone, art) than Broken Silence and still in early development, but you can follow us on twitter for updates if you're interested. If not, thank you still for the kind words :)
