Honestly, based on the screenshots for the game, I think both visual corruption and interference could work together if used well. I'm not sure how much interaction Snakey was supposed to have with the player - I wasn't sure if it was more like Clippy from Microsoft Word (where it just offers suggestions) or more like SmarterChild (where we could have conversations with it). It acts more like Clippy, so I think if you wanted to expand at all, it could start giving the player misinformation about what BASILISK is, or maybe guide the player to the horrific fate hinted at so far. I'm not sure, but there's definite groundwork to play with here.
