An engineer's drawing table where every level is a blueprint sheet. Drag back to draw a throw, watch the amber arc land and bring down towers of timber, stone and glass until every balloon and star crate has popped. Live dimension lines under the board show angle, pull, stones left and targets still standing.
A-01 · Path
Thirty sheets laid along one winding path, split into chapters such as Angles and Glass and Frost. Every sheet holds three stars for using few stones, and a hero counter tracks stars out of 90. A hint traces the green dotted line of a proven plan.
A-02 · Specification
Each sheet lists parts on site, the stone allowance and the mark for three stars. Clear it and a drawing stamp records stones loosed, targets popped, glass broken and score.
B-01 · Five-tower trial
Five fixed structures in a row against the clock. A failed one simply resets, and your quickest time and a work log are kept.
B-02 · Rival engineer
Three rounds on copies of one structure against a careful bot. Fewer stones takes the round.
C-01 · Engineer's journal
An eight-chapter story from the engineer's notebook, from The Commission to Counterweights, unlocked by the structures you bring down.
D-01 · Quiz
Eight questions per round drawn from 24 real facts on mechanics, balance and historic war engines, each with a short explanation.
E-01 · Setup
Haptics, a progress reset and the background switch. The animated background is a slowly drifting blueprint grid where compass arcs draw themselves and a measuring rule runs along the edge. Switch it off for a still sheet.
