'Evidence glow' is there to make evidence glow more that it usually does. By default, they are flat, bold colours. With the setting turned on, they kinda pulse. People kept missing them. We didn't intend to make a game about searching for evidence, our focus was more about piecing it together. We've seen what this game looks like when players are searching for that final piece they're missing, and that's not the game we wanted to make at all.
Glad to hear you enjoyed it overall, though, and thanks for chiming in.
We've got even weirder stuff on the way, so keep an eye out.
