SGCS's current dev phase is focused on asset importing and file structure. While the tools are made, actually adapting to the visual novel script to run in engine is one of the later steps.
One of the things currently being worked on is figuring out how to layer elements to give it a vintage texture. Specifically using code and filters that look right on mobile and desktop. While the scanlines and noise overlay can be toggled, it's an essential element for the default look to tie together the script's influences (80s comedies and bootleg anime OVAs).
We're still on the fence if the final game will qualify as T or M. For the time being, content ratings for the blog post will play it safe and choose M. (If you're hoping it'd be A, sorry to disappoint)
