JavaScript Playground 1.2.0

Achievements now celebrate key Tetris and Battle Tanks milestones at the moment players earn them.

Highlights

• See achievement unlocks during active play when reaching Tetris level 10, clearing four lines at once, or completing eligible Battle Tanks power-up and tactical challenges.
• Hear the Tetris music accelerate when the tower rises above two-thirds of the playfield, then settle back to its normal tempo when the danger clears.

Fixes

• Prevents live achievement notifications from appearing again when the final game result is recorded.
• Keeps achievement celebrations clear of phone touch controls so they never interrupt play.

Technical notes

• Adds rate-limited, server-validated achievement checkpoints for irrevocable in-game milestones without creating results, scores, leaderboard entries, or cumulative completion progress.
