itch.io

Not sure if that's the actual save data, but there's an AppData folder that looks like it could be it.
AppData is a hidden folder, so the easiest way to access it is to press Windows + R, and type %AppData%

Then it's .\Godot\app_userdata\Lovecraft Locker-Tentacle Lust

Are there any plans to add the boy animations to fap mode?

Using the maid outfits for the boys might also be an easy way to add femboys.

Maybe an option to give the girls some time to clean up? They'd spend more time in the locker without giving extra lust, but they'd also be less likely to shock other girls.
