Prototype Unity: Building Blocks

here is a video of a quick example of how I think that I want the building aspect of the app should look like from a basic point of view.

The blocks are “magnetic” like the real product will be

for the next prototype I want to take the object that is made in the “building” mode and add a rigidbody to it as a whole simulating that the player will now be able to play with what they have made.

Learning from this I now think that I want to create basic outlines / tasks to fill in with objects to make pre-designed objects that work as intended. This way there is a learning experience in the building aspect of the game.
