FUNDAMENTA is a game-tool — a playground where you first build and then play, without a fixed objective.

The goal is not to compete with Minecraft or Blender — it's to occupy a space between the two, accessible to the casual user and reasonably useful for those who already have experience.

For gamers, it's an open sandbox. For artists and developers, it serves as a block-building tool (level drafting) and allows exporting any creation as a 3D model in .obj format.

The controls are standard first-person, with full support for keyboard, mouse, and Xbox controller: walking, running, jumping, crouching, climbing, swimming, and diving. Construction happens in real time on a fixed grid, Minecraft-style, with cubes and some simple geometric shapes. There are also special blocks, with custom mesh and their own behaviors — they appear highlighted with a red outline in the selection menu.

The environment isn't just static: the day and night cycle features procedurally generated sky and stars, torches and light blocks illuminate the environment in real time, and the water has variations with caustics, underwater fogging, and physical flotation for objects that fall into it.

The software has two modes, switchable with F1 on the keyboard or Back on the controller. Interaction is the normal game, with gravity and collision. Creation is no-clip free flight, allowing you to work without anything getting in the way. A​dditionally, a photo mode can be activated at any time by pressing F2 on the keyboard or L3 on the controller, allowing you to capture your creations from the best angles.​

Each creation is an independent file: you can have several, switch between them at any time without losing progress, and delete the ones you no longer want. The pause menu centralizes video, audio, control settings, and the creation list. The interface is available in Portuguese and English.

As it is a software, the current focus is on construction tools and free exploration. Future versions should bring deeper interactions with the environment—damage, death, and game-specific elements—without sacrificing creative freedom.
