Glad you liked the concept. I think the world building/setting was bigger than it needed to be for a jam game and a lot had to be implied.
Yeah mixing the audio in 3d was tough. Made me appreciate when games transition from in-person dialogue to over the radio and still stay audible.
I had planned to add subtitles but ran out of time and had to cut them. I assume subtitles wouldn't disqualify the wildcard, but even if so, the accessibility is more important. My hearing isn't too bad but I watch most things with subtitles, to help absorb the concepts, so it wouldn't even just be for hearing difficulties. I think if I do anything this dialog heavy again, subtitles will be higher on the priority list.
