+
+### Session 7 - 2026-08-21 (Morning)
+**Status:** ✅ Mobile Touch Optimizations & Click Button Polish Added
+
+#### What was done:
+- Added comprehensive touch optimization CSS with `-webkit-tap-highlight-color`, `touch-action: manipulation`, and `user-select` controls
+- Implemented ripple effect animation on click button for visual feedback
+- Added pulse animation to the harvest button (subtle breathing effect)
+- Added glow flash animation on each click for satisfying feedback
+- Added touchstart event handler with proper preventDefault to avoid double-firing
+- Created responsive breakpoints at 768px and 480px for mobile devices
+- Increased touch target sizes (44px minimum, per accessibility guidelines)
+- Added overscroll-behavior: contain to scroll areas to prevent pull-to-refresh
+- Made footer buttons wrap and center on small screens
+- Enlarged harvest button on mobile (180px vs 150px desktop)
+
+#### Files modified:
+- `js/game.js` - Added touch event handler, ripple effect creation, click animation methods
+- `css/game.css` - Added touch optimizations, ripple animations, pulse effects, responsive breakpoints
+
+#### Next goals:
+- Achievement progress tracking in stats panel
+- Consider adding more sound variations or background music
+- Potential new building tiers or prestige milestones
