Bad Monday Simulator is a fan-made game that fuses the bullet-hell combat of Undertale with the absurd humor of Garfield. The project was created by three contributors: Lumpy Touch (pixel art), Spasco (programming), and Polarial (music). The central encounter is a parody boss fight against Sansfield, a strange hybrid of Sans and Garfield, set in the parody world Undergarf, where Mondays do not exist.

Story and Setting

The player takes control of Nermal, who finds himself in Undergarf and is forced into a battle with Sansfield. The game does not follow a deep narrative—it tells its story through the duel itself. The humor plays on Garfield’s hatred of Mondays combined with Undertale’s legendary boss mechanics, creating a surreal and entertaining crossover.

Gameplay

• Combat system: The battle is structured as a bullet-hell fight similar to Sans’ encounter in Undertale. Players dodge attacks with WASD, and there are no invincibility frames—every hit counts.
• Sansfield’s attacks: Beyond direct damage, attacks can inflict status effects like “karma” or poison, draining health over time. Healing items must clear the effect before restoring HP.
• PRAY command: Instead of a predictable ACT menu, PRAY triggers random effects. Results range from healing by the Pasta Fairy to destructive meteor strikes or absurd surprises like clowns appearing. This randomness makes every attempt unpredictable and funny.

Modes and Endings

The game features three difficulty levels: Normal, Hard, and the notorious Monday Mode. Each difficulty offers two endings depending on whether Sansfield is spared or killed. Altogether, there are six possible outcomes. Monday Mode is infamous for its speed, complex attack patterns, and unique finales, including bizarre outcomes such as Nermal becoming the origin of Mondays.

Features and Atmosphere

• A bizarre crossover of Undertale’s style with Garfield’s world.
• Challenging bullet-hell combat that demands precision.
• Unique pixel art crafted by Lumpy Touch.
• A chaotic soundtrack that blends tension with humor.
• High replay value thanks to difficulty modes, multiple endings, and the random PRAY mechanic.

Bad Monday Simulator is more than just a parody—it is a well-crafted fan project that both honors Undertale and subverts it with Garfield’s absurd charm. It delivers a difficult, funny, and memorable boss battle that feels familiar yet fresh. For fans of Undertale or anyone who enjoys strange internet crossovers, this game is a unique challenge worth experiencing.
