This one was interesting to me because in some ways is similar to what I tried to do in my submission, but you went in a very different direction with yours (and just straight up made a more complete game than I did lol)
The most impressive part imo were the 3d npcs walking around, but it wasn't super clear if they were buying my stuff or not. I did also really enjoy the little narrative segments in between cons. They add a lot of character and are just the right length to not distract from the main gameplay.
