Voxelantis

Voxelantis is a sandbox building and survival game set in procedurally generated voxel worlds. 
Here you can build elegant structures and construct ingenious machineries, or adventure into wild lands and uncharted territories to discover valued items or fight dangerous creatures.
In the beginning you are mysteriously stranded in a big flat world and lost your way back to your small home planet. If you want to get back, you must survive and build your way back to your home planet. Only then can you reclaim the planet and rebuild it into a dream world of your own design.

You can design and build elegant structures with deformable voxels (full blocks) and subvoxels (partial blocks).
Partial Block Placement
You can move the cursor around to select different block shapes (full or partial blocks). After you placed a block of the selected shape, this shape will automatically be chosen for the next placement.

Round or Sharp a Block
You can make a block rounder or sharper by striking at one of its corners or at one of its face centers with a hammer.

Batch Building
You can place multiple blocks at once in the batch building mode.

In Voxelantis your can also conceive and construct ingenious machineries and devices controlled by electric circuits.
Mechanical and Electronic Device Items
Voxelantis provides a large number of standard mechanical and electronic device items for building sophisticated machineries and devices controlled by electric circuits.

Mechanical and Electric Circuit Simulation
You can build electric vehicles, robotic vehicles or even robots, and use them to travel faster or do things automatically.

In order to get back to your home planet, you need acquire some rare materials for building a quantum portal, this is the only way to return home. And some of those materials are available only in the survival mode.
You can explore the world to gather resources, unlock recipes and craft tools and weapons. Then you can defend yourself and fight dangerous creatures in order to survive.

When you finally return, your home planet has become empty, so it is a fresh start where you can remake the world however you imagine.
When you are ready to take another adventure, you can use your home planet as the base, bring a few things with you, then go to some other spherical world for a new adventure. You may bring some trophies from such adventures back to decorate your home planet.
