Bridge Builder

You are given a set of materials and a vehicle to get across a gap. The physics drive everything, so a bridge that looks solid can buckle the moment weight rolls onto it. Playable on desktop, phone, or tablet in landscape, with touch controls or mouse and keyboard, it runs straight in the browser with no install. Four locations offer progressively trickier spans that demand trial, error, and occasional rebuilding.
