Bad Time Simulator

There certain conflicts you don’t need to beat your opponent with raw power, only exhibit your patience to live. Bad Time Simulator has players jump straight into the infamous Sans Fight from Undertale, where a 1 HP skeleton is a nightmare with a flurry of unpredictable attacks. You don't need to complete the entire storyline or install the original game, you can jump directly into the fight in your browser and tackle this task yourself.

Why Is It So Hard to Beat Sans?

The fight with Sans in Undertale occurs at the end of the Genocide Route, a plot path focused on defeating monsters. Bad Time Simulator recreates that confrontation with relentless waves of flying bones, lasers from Gaster Blasters, and a gravity mechanic that forces players to constantly change their movement.

You control a red heart within a small battle arena. A single wrong dodge can deplete your health bar, while the Karmic Retribution effect continues to drain health after you take a hit. Sans dodges all direct hits, so victory depends more on your ability to withstand the attacks than your strength.

How to Play Bad Time Simulator

The arrow keys or WASD move the heart in four directions. Use Z or Enter to confirm an attack, and X or Shift to go back or skip dialogue. When the soul turns blue, you must utilize gravity and jump using the up arrow or W to overcome obstacles.

The easiest way for beginners to fail is with the light blue bones. Unlike the white bones, they only deal damage when you move. Dodging reflexes, which are useful in other levels, become a mistake here. Sometimes the best way to survive is to give up control entirely.

Tips to Survive Without Battles

• Practice Each Attack: The Practice and Single Attack modes allow you to focus on the tough areas without repeating the full battle over and over again.
• Slide in brief spurts A few keystrokes can prevent you from going over the gaps between rows of bones.
• Watch and dodge. — Before you do anything watch which way the bones are going and where the laser beam is.
• Save your health until the late game. Small blows can put you at a disadvantage because of the persistent damage impact .
• Be patient with special moves: Sometimes Sans won't attack but waits for you to move. Don't mistake silence for a signal to act.
