11FL?

Clear 10 floors to climb from the 1st floor to the 11th. On each floor, tap tiles to flip them and match every identical pair. Matches stay up, and a mismatch flips back.

Every floor has its own time limit. Running out of time drops you to Ground Floor. Then you try again.

The clock starts when the 1st floor appears and never stops, retries included.

Accuracy: a green 10/10 means you never ran out of time. If you did, the red number is the floor you first ran out of time on. Mismatches don't count.
