Details on how to play Bad Time Simulator

You are in charge of a heart-shaped SOUL in a small, rectangular area on the battleground. Sans lets out scary magic that combines patterns of bone barrage, platform dangers, and deadly laser beams. The moody music, which sounds like a mix of Megalovania and Monty on the Run, keeps your heart racing as you try to avoid every attack.
Easy-to-use controls and core game mechanics
The rules for the game are simple, but you have to be very good at them to master them:
Use the arrow keys to move your SOUL around the screen and avoid danger.
Stay Still: Don't move at all when blue attacks happen to avoid getting hurt.

Features and Tips

Remember your attack patterns. Sans is based on rhythm and order. You have a huge advantage if you can remember his bone barrage.
Master Blue Attacks: Stop the game right away when blue bones appear on the screen.
Reflex and Precision: Stay calm when things get tough; responding too much in small places is bad for your health.
