What’s one bug that turned out to be a feature in your game?

While we were working on Heroes of Warland (a mobile FPS we worked on) at Juego Studios, we had this weird particle glitch in the early multiplayer prototype, explosions would occasionally leave a smoky trail that hung around for way too long. At first, it looked like a rendering issue. But while we were testing it, we kind of started using the smoke as cover. We decided to time grenade throws just to block enemy vision for a few seconds.

That wasn’t the plan at all, but it completely changed how matches played out. Instead of removing it, we tweaked the particle lifetime and built a proper "smoke bomb" mechanic around it.

Love to hear your stories.
