Indie Business & Design 💼
How Goose Goose Duck Won Big by Staying Small
Shawn Fischtein, co-founder of Gaggle Studios, explains how Goose Goose Duck became a global social deduction hit by staying small, truly free, and relentlessly community-first. The team built seamless social tools into the game, refused to lock content behind paywalls, and avoided whale-driven monetization. Instead of chasing huge influencers or big funding, they focused on organic, clippable moments and small, tight-knit Twitch communities. Five years later, they argue agility, restraint, and strong IP matter more than scale in an overcrowded market.
How Fruit Ninja’s Designer Decides Which Indie Games Are Worth Years
Fruit Ninja and Jetpack Joyride designer Luke Muscat explains how he avoids the indie nightmare of spending years on a game nobody wants. He prototypes quickly, pairs each prototype with a devlog, and waits for clear signals—views, engagement, wishlists—before committing to 18 months of full production. That data-driven approach led him to shelve a game he loved and double down on Feed the Deep instead. He also reveals how an 8-week mobile port of Feed the Deep brought in around $70k.
Rendering & Engine Tech 🔧
Interactive Volumetric Fog in Unity with One Compute Shader
Instead of particles or Unity’s built-in fog, this deep-dive shows how to get interactive ground fog from about 200 lines of compute and shader code. The fog density is simulated entirely on the GPU, using math-defined wind and swirl around the player plus noise-driven regrowth. A custom ray-marched volume shader turns that flat density map into thick, height-tinted fog that reacts to movement and static obstacles. It’s packed with practical patterns—ping-pong textures, cheap noise, object-space ray marching—you can reuse in many VFX.
From Unity to Vulkan: Writing a Lightweight GPU Library from Scratch
Sebastian Lague dives into Vulkan to create a small rendering and compute library in C++, complete with C# bindings. He covers the essentials of setting up a Vulkan pipeline, managing multiple frames in flight, and rendering meshes with depth and instancing. Lague then brings the GPU to life with compute shaders, simulating thousands of bunnies and a full fluid sim, and reuses the framework for text rendering and a simple UI. It’s a hands-on tour of low-level graphics that’s immediately relevant to engine-curious game devs.
Physics, Tools & Automation 🧪
Auto-Rig Anything: Trees, Monsters, and Destruction with UE5.8 Data Flow
Epic’s rigging and destruction experts showcase how UE5.8’s Data Flow turns painful manual setup into reusable, non-destructive graphs for skeletons, physics, and destruction. They use the new skeletonization node to auto-rig weird meshes—octopus, dragons, starfish guns—then drive them with Control Rig Dynamics for fast runtime simulation. Along the way, they reveal tricks like transferring deformation data from low-res to high-res meshes and converting geometry collections into skeletal meshes.
From Box2D to Box3D: Erin Catto’s New Physics-Driven MMO
Box2D creator Erin Catto walks through his path from hacking on calculators and PS2 physics to shaping one of the most influential open-source engines in games. He explains how determinism, smart APIs, and wide-SIMD solvers drive modern physics performance, and why he’s now building Box3D as open source. All of this feeds directly into Legend of California, a gold rush–era multiplayer survival game with fully simulated trees, ragdolls, and voxels running server-side.
