Desk Grid Bastion is a bright tabletop blueprint defense game where every turret placed across the open drafting grid reshapes two simultaneous ground BFS flow fields: West-to-East and North-to-South.

Build economical Pellet Turrets to lengthen dual-axis corridors, freeze tight intersections with Frost Slow emitters, intercept soaring Flying Gliders with Swarm Rocket AA racks, eliminate distant targets with Sniper towers, and discharge leaping arcs from Shock Towers. Live path preview highlights and strict anti-seal checks prevent trapping either axis while upgrade & 70% sell/refund controls let you reshape defenses across three drafting boards.

Disclaimer: Independent offline strategy game with local JSON score logs, synthesized WAV audio, and optional documentation/donation links.
