This is definitely a very unique experience, and a technically impressive title. This is probably the best application of the theme that I've seen. And it feels good to match two karmically matched folks. And it is kinda cool to play god.
For me the controls were pretty intuitive as I'm used to working in Unity/UE4 with WASD + Q/E, but maybe you could have included that bit in with the instructions for those less familiar with 3D package standards.
I believe there is a lot of potential here, and I can see that this was no small investment. I appreciate that. The way the characters will interact and then part ways, and repeat. It's very impressive stuff!
There exists very real challenge in the game, when it comes to tracking peoples Karma. Not only are they always moving, but you must remember that the graphic is actually a reflection of the person they spoke with! A lot to keep track of. Could use some difficulty tuning / progression. Maybe the map starts smaller and grows... Just a thought.
