Terravox is a 3D sandbox video game. You appear only with a set of simple tools - a pickaxe and an axe. Everything else will need to be obtained independently.
You can create new blocks from the collected ones. For example, you can create planks from logs and steps from planks. With blocks collected and crafted, you can build buildings that are only limited by your imagination.
There are no mandatory goals to achieve in the game, which gives players a lot of freedom in choosing how to play the game.
