Bad Time Simulator is a fan game inspired by the infamous Sans boss fight in Undertale. The game is designed to challenge players with merciless bullet-hell mechanics, requiring quick reflexes and precise movement to survive. Players control a small heart (the soul) that must evade an endless stream of attacks from Sans, including fast bones, Gaster Blasters, and gravity-manipulating obstacles. The game perfectly simulates the challenge and chaotic atmosphere of the original fight, with multiple difficulty levels, including an Endless Mode for players seeking an even greater challenge.

Bad Time Simulator is an interactive web browser game, so Undertale fans can test it without having to replay through the entire game. The blocky graphics resemble the original battle, and the rapid, reaction-based gameplay is fun.

The game gained popularity due to the fact that it is a good opportunity to practice dodging and experience one of Undertale's greatest battles without needing to finish the entire Genocide Route. Just like the Tiny Fishing game, Bad Time Simulator is generally a good but extremely difficult game that will be of interest to fans of bullet-hell challenges and players who want to attempt the thrill of battling Sans.

Gameplay

In Bad Time Simulator, the player is in control of a little red heart, which symbolizes their soul, and must survive the constant attack of Sans. The game is similar to a bullet-hell, where the player must avoid a vast number of quick and abrupt obstacles. The attacks consist of moving bones that must be dodged or jumped, Gaster Blasters that fire hazardous energy beams, and areas of altered gravity that make it more difficult to move. Unlike typical turn-based RPG combat, there are no turns for the player to attack—survival is the sole objective.

The game is available in different difficulty levels: Normal, Hard, and Extreme. This provides an opportunity for players to challenge their speed in different ways. There is also an Endless Mode, where players face endless attacks and try to last as long as possible. The movement is done using the arrow keys, which demands timely precision to navigate through the chaos.

One of the toughest aspects is the distinctive blue and white bone rule: blue bones hurt the player only if they are moved, and white bones hurt upon contact. This forces players to balance when to move and when not to, with its graphics like those of the Swing Monkey game. With its fast and demanding gameplay, Bad Time Simulator is a thrilling challenge of skill and endurance.

How To Play

In Bad Time Simulator, the player controls a little red heart named the soul and attempts to survive numerous attacks from Sans. Bad Time Simulator features a bullet-hell genre, with quick reflexes and careful movement being essential to survival. The player controls the soul using the arrow keys in a small battle arena, dodging various hazards such as flying bones, Gaster Blaster shots with constantly changing speed, and zones with changing gravity. Unlike typical RPG battles, there is no space to attack—only to defend.

One of the most striking aspects of the game is the white and blue bones contrast. White bones will cause pain when touched, and blue bones will cause pain to the player only when they go through them. Test your reflexes in Color Rush! Play now! That is, players must remain still when approaching blue bones and exercise caution when going through white bones. Other attacks affect the environment by causing players to jump or with reversed gravity.

The game has several levels of difficulty: Normal, Hard, and Extreme. An Endless Mode, in which the difficulty is unlimited, also exists. The goal is straightforward: live as long as you can. The players need to listen, get ready to be attacked, and interpret movement patterns in order not to get injured and continue fighting Sans.
