1. Added Relax Mode:
You can now enable this mode by clicking the icon in the "About" menu. As it's still in testing, it's currently available as a preview. Once enabled, the anti-cheat system activates—achievements can't be earned, stats won't be recorded, and the game won't count towards the leaderboard.
In Relax Mode, the empty row at the top (i.e., the mask row) stays fixed. Players earn points for each cleared line, and a new line is automatically added. Conversely, when a line is added due to a mine trigger or full grid, points are deducted, but no new line is added and the game doesn't end.
2. Fixed issue where mines in the top mask row were incorrectly triggered during consecutive line clears:
The game follows a “add line before clear” logic. In some cases, both adding and clearing lines happen in succession. For example, clicking a mine causes all mines in that row to explode and be cleared. At the same time, a new line is added, which may trigger the auto-reveal of adjacent empty tiles (with value 0). If all non-mine tiles in the new line are revealed, more clearing and adding can follow.
New lines are created by copying the previous one. If the mask row is at the top and more than two consecutive clears happen, the two rows above it may not yet have mine data. If auto-reveal continues, these uninitialized tiles may open early, causing unintended mine triggers. This has been fixed by disabling auto-reveal of adjacent blanks in the top area, avoiding premature tile openings.
