All 4 games (simon_says, tic_tac_toe, memory_match, 2048):
- Changed sizing to use min(width, height) instead of just width
- Grids now scale proportionally on both axes
- All UI text now uses text_scale=2 for better visibility
- Games fill more of the screen properly on portrait mode
Fixes:
- Simon Says buttons now square grid on any orientation
- Tic-Tac-Toe grid centered vertically using full screen height
- Memory Match cards use smallest dimension for square sizing
- 2048 tiles scale and center on both axes
- All text (scores, menus, game over) now 2x larger
2048.lua:
- Removed hardcoded TILE_SIZE and TILE_SPACING constants
- Added get_tile_size() function that calculates tile dimensions based on screen width
- Added get_grid_start_x/y() to center grid
- Updated draw() to use dynamic sizing for all tiles
- 4x4 grid now scales proportionally on any screen size
