Description
Note: the following information is based on the trial version and may not apply to the full version of the game.

Story-wise, Lust Friend is similar to its predecessor in that Magrut finds himself mysteriously transported to a world dominated by succubi. However, in this world succubi appear to be the only inhabitants, unlike the world of Lust Grimm. Furthermore, when he wakes up he encounters Fess, a powerful succubus and a major villain in the previous game, who helps Magrut adjust to this new world. She tells him that, if he helps her build a tower for her kind, she will return him to his former world.

The gameplay is also similar to that of Lust Grimm. The player controls Magrut and can move around a 2D map to interact with people and objects. Enemies on the map will pursue the player and battle is initiated on contact. Battle is turn-based and revolves around making the enemy orgasm before they do the same to you.

There are several notable differences from the previous game. Lust Friend has a day-night cycle that progresses in real time. This affects background lighting and enemy strength (enemies do increased damage at night). The power of skills will increase the more the player uses them. Enemies can now be defeated without attacking them through the new Conversation system. The player can use a variety of dialogue options to raise an enemy's opinion of them. By doing this enough they will trigger a "Friend Flag", which unlocks an option to end the battle. Winning in this method rewards the player with unique items.
