Behind the Game: Why “10-Second Rule” Was Created

The idea for 10-Second Rule was born from a personal struggle—feeling stuck in the endless loop of daily life.
After a routine day of university, I realized how repetitive everything felt.
Then, I watched a speedrun video online.
Seeing a player clear a challenge in just seconds inspired a thought:

“What if a game could be resolved in just 10 seconds?”

That idea lit a spark, and I began developing 10-Second Rule.
My goal was to deliver intense tension and rapid-fire satisfaction in a game anyone could pick up.
I can't wait to see how players experience it.
