Review

Detra Mental Decimation is a fan-made rhythm game that leans on the FNF formula without pretending to be an official entry. Its strongest asset is the two-week split: four songs in Week 1 and three bonus tracks in Week 2, paired with a character who visibly evolves between them. The seven named songs each carry their own rhythm, so players cannot coast on a single memorized pattern. Keyboard arrow controls keep the barrier low, but accuracy demands real concentration. It suits players who enjoy timing-based music challenges and do not mind repeated attempts to clean up a run.

About this game

FAQ
Is Detra Mental Decimation an official Friday Night Funkin' release?
No. It is a fan-made rhythm game inspired by FNF. The original programming comes from ninjamuffin99, with art by PhantomArcade 3K and Evilsk8r and music by Kawai Sprite, but SkullZMinus developed this specific project as a separate fan title with its own characters and songs.
How many songs are in Detra Mental Decimation?
Seven original songs are included. Week 1 contains four of them, and Week 2, labeled BONUS, contains the remaining three. The named tracks are Retricus, Covetous, Terminus, Embark, Facade, and Compel, each written with a distinct rhythm pattern rather than a shared template.
What controls does Detra Mental Decimation use?
Play is built around the arrow keys on a keyboard. When a note reaches the hit zone, you press the corresponding arrow key to score points and extend your combo. There is no indication of touch or controller support, so a standard keyboard is the expected input method.
What changes between Week 1 and Week 2?
Two things shift. The character evolves from a gray body with black clothes, an orange cape, and orange eyes into a bicolor half-black, half-gray form with a red cape and tie. The difficulty also increases, making the three BONUS songs harder than the four songs in Week 1.
Is Detra Mental Decimation suitable for younger players?
The source material describes it as a family-friendly rhythm challenge, and the gameplay consists of pressing arrow keys in time with music. There is no mention of graphic content or mature themes, so the presentation appears aimed at a general audience, though younger players may find the later songs difficult.
How do I improve my accuracy in Detra Mental Decimation?
Practice each song's pattern in a low-pressure setting to build muscle memory, and focus on the beat rather than the visual notes. Short breaks between attempts help you avoid fatigue, and listening to song previews lets you anticipate tricky sections before they arrive. Staying relaxed keeps your hands steady.
