Very good game.
But if I had to give constructive criticism it'd be about the story. The story is kinda too bland& too simple.
It'd also be good if it had mentioned how Native American religious rituals were banned by law in USA due to religious bigotry.
Also, for using rendered images for story, I think it's smart. Making animations for story would be really hard, but posing the models & taking renders/screens is easy. Instead of not having a story, you came up with a simple, but clever method that's not normally used in high budget games. Really cool!
