Build a fragile fortress, then smash it apart in a physics sandbox.
About Build & Destroy - Fortress Duel
Build & Destroy - Fortress Duel is a physics game that splits every session in two. First you construct a fortress meant to be tricky to topple, then you aim at it and watch the pieces collapse under the impact.
The creator says the concept came from years of playing Angry Birds and wondering why games like it rarely let players design the levels. Here you make your own challenge instead of only solving premade ones. The creator used Codex and Three.js, and the game came 256th of 945 at Vibe Jam 2026.
Planning is where the puzzle and strategy come in. Working out how a structure will hold, and where it will fall, makes building the puzzle as much of the game as breaking it.
