This is a block assembly simulator.
You can use your mouse to manipulate the Ui, summon the blocks, and place them in the desired position.
Keyboard operations allow you to install, erase, or redirect blocks.
You can use a variety of colors to color your installed blocks.
If you've installed the block, you can save it, and you can call it up.
The background music does not exist at the momentarily. I have an intention to add it later.
Assemble the blocks that you want to have!
