## What is 0 to 99?

0 to 99 is a fast mobile card game about one simple decision: is the next number higher or lower?

  Each new card is compared against the previous one.
  Swipe right if the number is higher.
  Swipe left if the number is lower.

  The rule is simple, but the pace keeps rising.
  As the timer tightens, every decision has to be faster and cleaner.

  Features:
  - instant higher-or-lower gameplay
  - short runs built for quick retries
  - rising speed and time pressure
  - swipe or tap-area controls
  - clean portrait play tuned for mobile
