Bad Time Simulator

Bad Time Simulator is a fan-made game inspired by the legendary battle with Sans in Undertale. It's not a lengthy RPG – it's a test of reflexes, memory, and composure under immense pressure.

In the game, you'll face Sans directly in an extremely intense battle. The gameplay focuses entirely on dodging a barrage of attacks like bones and Gaster Blasters while simultaneously counter-attacking to defeat him.

How to play Bad Time Simulator

• Players control a small heart within the battle arena.
• Dodge waves of bones that appear in a fixed rhythm.
• Avoid lasers from Gaster Blasters.
• Remember the attack patterns, as most attacks follow a repeating pattern.
• Attack Sans to accumulate enough hits and switch phases.

The game is divided into several phases, including:

• Phase 1 requires players to memorize the rhythm and limit healing to avoid getting caught in a constant healing loop.
• Phase 2 significantly increases the speed of the skeletons, forcing you to concentrate intensely and only heal when absolutely necessary.

In the final moves, standing near the center and remembering the direction the skeletons spawn is crucial to victory.

Bad Time Simulator is not for the impatient. You will die. Many times. But if you remember the pattern, maintain a good rhythm, and don't panic when you're down to 1 HP… you can absolutely defeat Sans.

And when the victory message appears—you know you've just overcome one of the most challenging reflex tests in the Undertale fan community. Discover the new game Bad Piggies, funny and creative.
