Hydraulic Span Engineer

Hydraulic Span Engineer is a 60 FPS 2D structural bridge physics and drawbridge
engineering puzzle game across three scenic river and canyon stages.

Construct road decks, timber braces, steel trusses, tension suspension cables,
and active hydraulic pistons within each stage budget. Toggle split joints so
your drawbridge opens cleanly during the river vessel pass phase, then locks
shut again as sedans, delivery vans, and heavy dump trucks cross to the goal.

Features:
- Real 60 FPS truss mass-spring stress solver with live tension and compression overlay
- 5 structural components: Road Deck, Timber Brace, Steel Truss, Cable, Hydraulic Piston
- Split drawbridge joints with automated or manual hydraulic lift for vessel clearance
- 3 river and gorge stages plus Casual, Arcade, and Turbo difficulty modes
- Real 16-bit PCM WAV audio, persistent high scores, CSV export, and EN/VI UI
