So, Since we separated the scripts for each route, We wanted to start off day 4 making full use of it.
So the morning interactions with Kayla and Alex are being split up per route.
Some differences are subtle, some are major, Cousin route being a pretty major alteration that feeds off something you were able to get away with day 3.
In addition to this, an additional scene was added for Kayla, if you purchased the BDSM outfit for her. You will have the option to either do the BDSM scene, or your normal route scene. The BDSM scene with also allow you to give Kayla an alternate name to call you by, this option will come up again, and will also be available for other characters as well (if you enabled bdsm by buying the outfit)
Most of the rendering is done, just a few more things to button up.
