S1 Christmas Event
HO HO HO! Lust theory: “Christmas Story” is finally here!
 And just in time for Christmas! We worked really hard to make it the most jolly experience for you, our dear players. Okay, that seems like enough sucking up, he he, let’s get into the good stuff.
Join us in this Christmas adventure, where you get to play a role as the new manager working alongside “Santa” while SHE tries to prepare everything in time for the busiest day of the year.
In between packing presents, running away from raged reindeer, and toxic potions, try not to die from the excruciating cold weather. And what better way to keep warm then having sex with all the girls.

Installation Guide

1. Extract and run

Developer Notes

Welcome to Echoes of Lust Season 2! We are adding a new gameplay element called “Angle”. Now, on some images, a button will appear on the right side of the screen that will change the angle of that image. Free roam is disabled in S2E1 since we are just starting up. Free roam will become available again in S2E2. We wouldn’t want to spoil it for you so just play it.
