Replace continuous free-form movement with discrete 20x50 grid-based gameplay featuring asymmetric movement mechanics: - Blue/Red teams with 3 units each - Zone-based movement: orthogonal (4 dir) in offense, diagonal (8 dir) in defense - Alternating turns with click-to-select, click-to-move input - Fog of war: 3-cell Chebyshev vision radius per unit - Defense speed nerf: skip every 4th move in own zone - AI opponent that chases flag carriers and advances toward enemy flag - Collision resolution: defender wins in their zone, lower ID wins in neutral Implements all 3 phases from the plan: - Phase 1: Playable grid with hot-seat two-player - Phase 2: Fog of war + defense speed nerf - Phase 3: AI opponent Deleted obsolete files: Flag.cs, Unit.cs, RouteDrawer.cs, SimpleAI.cs, Visibility.cs Co-Authored-By: Claude <noreply@anthropic.com>
