Widescreen Support
Tetrogue now fully reflows to your window instead of letterboxing — every screen (menus, map, battle, shops, events) redraws to fill the available space, rather than pillarboxing to a fixed 16:9 box.
Six aspect ratios supported end to end: 16:9, 16:10, 21:9, 32:9, 4:3, and 5:4.
New aspect ratio picker in Options → Display for windowed mode.
Window resizing and maximizing now follow whichever aspect ratio you've picked in Options → Display, instead of always being locked to 16:9.
The battle scene's enemy panel, platform, and battlements now expand to use the full width on wider ratios instead of leaving the extra space empty.
New Gems & Relics
New relic: Double Edged Sword — doubles your own damage, but also doubles the garbage-line count of every enemy attack.
New relic: 7 Piece Randomizer — pieces are now drawn from a proper shuffled bag per shape category instead of pure random chance, so you'll see a more even spread of pieces.
New relic: Mythic Forge — unlocks a 5th, Mythic gem rarity tier above Legendary. Existing gems can now be upgraded one tier further than before.
New gem: Cursed Gem — deals double a Raw Gem's damage, but gives you garbage lines of your own.
New gem: Mirror Gem — copies the effect of the gem in the slot above it.
Piercing Gem reworked: now destroys the target's armor entirely, and if the target had no armor to begin with, the hit chains through to the enemy behind it too.
"No More Drought" reworked into "There When You Need Me" to avoid overlap with the new 7 Piece Randomizer relic — instead of guaranteeing an I-piece after a drought, it now guarantees a long piece whenever your board has a real 4-line well open.
Fixes
Fixed a previously-visited shop or gem vendor staying re-enterable from the Map screen for the rest of the stage — it now closes as soon as you visit another node, as intended.
Fixed the Options → Controls group headings getting clipped by the next row at Large/Huge font sizes.
Fixed star-rating displays (e.g. gem tooltips) logging a harmless but noisy error for the new Mythic tier.
Quality of Life
Added a floating "Join the Discord!" callout next to the Discord icon on the main menu.
