What is SimplePhysics?

SimplePhysics is a premium physics-based engineering simulator that allows users to design structures and test them against realistic physical forces. Its unique value proposition lies in the balance between rigorous engineering (cost-efficiency and stress analysis) and sandbox-style destruction (explosions and ragdoll physics). While highly rated, it currently operates as a legacy title with its last significant update in 2017.
