About this game

Frieren and Fern in the Lewd Dungeon by Kazumatsu is a parody RPG based on the Frieren universe. A dungeon emanating mind-affecting energy appears, and you play as Fern uncovering its mysteries while encountering Frieren cast members and outsiders pulled in against their will.

Built in RPGM as a fantasy female protagonist adventure with monster girl encounters and lesbian routes, the game runs the parody premise through escalating dungeon corruption.

Expect 2d game, 2dcg, adventure, animated, combat, fantasy, female domination, female protagonist, lesbian, monster girl, oral sex, parody, RPG, sandbox, scat and urination content threaded into a fanfic-dungeon RPG where Fern's psyche is the actual battlefield and Frieren makes increasingly compromising cameos.

Changelog

v0.9
(25.03.2026) Succubus Queen battle is implemented Win scene (with and without scat enabled) Lose scene (with and without urination enabled) Many battle lewd-action scenes (normal tags) Minor damage rebalancing

v0.3.1
(06.06.2025) A bug was found in Frieren and Fern in the Lewd Dungeon. If you solve the puzzle with a bunch of statues in an unusual way, you can get soft-locked(( The bug has been fixed. The fix is available at the link, and I also decided to include a save file with a complete playthrough.
v0.3
(27.03.2025) 7 unique scenes, totaling 9 animations are now available! With different dialogues and situations for each scene, the total number of variations is even higher. The battle with Ubel is a training battle, so you can’t actually die here. Sound improvements. Spell changes: The damage from spells has been slightly increased with level progression. Cheats: Now you can get a bunch of spells and potions by using a secret artifact. You can find it by talking to a mysterious figure outside an abandoned house. Simply knock on the door of the house Fern refused to enter. Game menu changes: Now you can exit to the main table from the game menu. Also, you can open the game in full-screen mode. First foot fetish scene adjustments.
v0.2.5
(05.02.2025) 2 new scenes (One replaces the very first scene from the initial version of the game, and the second is the winner of the vote) A bug in the quest "Prepare for the descent into the dungeon!" has been fixed. Specifically: when talking to Frieren at the dungeon entrance, if the character was positioned above Frieren, it caused a softlock. Some minor adjustments to the timing of scenes. Small, unnoticed playback bugs were detected during testing.
v0.2
(20.12.2024) The update introduces 6 brand-new, unique scenes with a large variety of new animations, with up to 5 animations in some scenes! A new dungeon floor with new puzzles—solve them, and you'll earn "rewards")) The main storyline progresses further, with Kanne and Lawine now participating in the dungeon expedition. A looped scene awaits you as an additional reward at the end of all the quests in the update. Additionally, in update 0.2.1, old animations have been reworked, and bugs related to their playback errors have been fixed. Previously, you could miss small parts of some scenes where dialogue played as if "an event is happening," but you were already seeing its outcome. Additional optimization has been made for scene playback. Now, during scene transitions, the moments without images between the appearance of new animations and the disappearance of old ones should be significantly shorter. The gallery has been expanded, and all new scenes have been added to it.
