GIGANTUA.
About

Gigantua is Daniel Infuehr.

An independent developer in Vienna, Austria. I write the engines, the tools and the games myself: the renderer, the synthesiser that makes every sound, the store integrations and the build pipelines that ship them. No publisher, no investors, no ads, no tracking.

This site is where you buy directly from me. You get a plain download without a launcher or an account, and no store takes a cut.

The Wraith interceptor over the neon grid

Seven Worlds: Neon Odyssey

A twin-stick arcade space shooter: seven planets, five ships to buy and fit, gravity wells that bend the mesh and your shots, guardians, sieges and an arcade mode. Everything on screen and every sound is generated in real time by the game's own engine. There are no sprites and no audio files.

One engine, every screen

The game runs on one C# engine. Each platform gets a thin host for its window, input, audio and store; the engine never knows which platform it is on.

EngineC# / .NET 10, SkiaSharp + direct OpenGL for the grid, a spring-mesh simulation under every frame, HarfBuzz text in 38 languages including right-to-left scripts.
SoundA procedural synthesiser and music sequencer: every effect and every track is computed per sample. No sound files ship with the game.
DesktopAn SDL3 host for Windows, Linux (Steam Runtime) and macOS (one universal, notarized app); Steamworks and Epic Online Services integrations.
Mobile, TV, car, watchA .NET MAUI shell for Android phones and tablets, Fire tablets and Fire TV, Android TV / Google TV, Wear OS with round-screen layouts, and Android Automotive.
VRA hand-written OpenXR host for Meta Quest: the game's frame wraps a dome around the player, Touch controllers map to the pad.
AppleiPhone, iPad, Mac Catalyst and a separate UIKit host for Apple TV with the Siri Remote, all built from Windows on a remote Mac.
LG webOSThe whole engine ported by hand to dependency-free JavaScript and WebGL 1, because that was the only way onto the TV; measured at 58 fps on a 2020 LG OLED.
StoresOne purchase model, eight payment systems: Google Play Billing, Amazon IAP, Microsoft Store, StoreKit, Meta, Steam Inventory, Epic Ecom and PayPal, with replay-safe delivery.
