Thanks for playing!
I had a freezing sound effect ready to hint at that, but unfortunately we ran out of time to implement all the sound effects into our game. Another hint was the fact that all the people before you were getting turned to stone statues, and you were given a lessened version of the freezing effect from the artificer's freezing bullet thanks to the protection of your amulet. If we had more time, we could've also delved deeper into the lore of the amulet and found more creative ways to deliver that item info. Even something like a dark-souls like item description could've been a good idea.
But thanks again! We appreciate the input. :)
