2 Triangles and 2 Cubes + The weapon and Thruster Block.
Left Mouseclick adds a block, right click deletes the one you are looking at.
Block Rotation is on the keys Q and E. Mousewheel to switch between the blocks.
For the next updates:
- Save/Load function
- New block preview icons
- Collisionbreaks and more
But until the significant things are not done in development the built ship cannot be played and tested to destroy asteroids.
