Visual Novels lead the player by the hand, but Photo Hunt is too complex game to demonstrate the value of each choice

Walkthrough help you progress through the game, where the player needs to go to advance the plot, how many love points of a given LI you should have, and the game warns you about the consequences of your choices before important choices.
The most important choices are the routes for LIs, the romance route and the corruption route. The corruption route can lead to sharing scenes, and sometimes sharing scenes are avoidable, sometimes they can lead to interesting scenes.
Activities such as exercising in the gym, for example, raise stats that can unlock special options in certain scenes. The value added by such activity is given after the scene. By spending time with LIs and by talking, you can earn love points.
Adding stats, adding love points, and even changing the route for a given LI is possible through the cheat menu in Shawn's cheat mod.
