Assets

Each package is split into small assemblies, so you take only what your game needs.

Card Kit

A game-agnostic card engine. Bring your own card data, rules and art, and skin it.

  • Pure C# rules core: board, lanes, effects, turn resolution, AI what-if simulation
  • Card feel: tilt, foil, drag & drop, flips, pack opening, dissolve
  • Game shell: settings, audio hub, save/load, localization, achievements, rebinding
  • Covered by automated tests
Coming soon Unity 6 URP

RPG Core

Engine-agnostic math for RPG combat, ready to plug into your own skills and damage types.

  • Deterministic RNG for replays and saves
  • Added / increased / more modifier buckets
  • Mitigation formulas and hit rolls
  • Modifier lifecycle
In development Pure C#

How the packages are built

Logic without the engine

Rules live in assemblies with no Unity references, so they run headless and are easy to test.

Take only what you need

Visuals, rules and app shell are separate. Use the card feel with your own rules, or the reverse.

Documented and tested

Every package ships with a full README, a changelog and an automated test suite.
