Here are some things the developer wrote about it:
You can build (small) constructions, using basic blocks, roof blocks, and some specialized pieces like windows and doors. You can choose the color of each piece (and change them later).
Everything can be controlled with the mouse, but it’s also possible to use the keyboard for most of the commands, making “routine building” more effective, and there is a minimum of text involved, to make it easier for kids,
You can save your models, or save pictures of them (.bmp, .jpg), even reuse a complete model as a part in another model.
“BlockCAD” includes most of the blocks you know from Lego standard sets, but misses some blocks you would need to build special stuff (like trains for example).
Another thing that really makes BlockCAD enjoyable for me is how it manages to stay interesting even after playing it multiple times. Many games feel repetitive after a while, but here, the experience still feels fresh because of the small details and different ways you can approach the gameplay. As you continue playing, you naturally start improving and understanding the mechanics better, which makes everything feel more rewarding. I also appreciate the balance the game maintains—it’s not too difficult, but it’s not too easy either. You can play it casually for a short break or spend longer sessions without getting bored. That flexibility is one of the biggest reasons why I keep coming back to BlockCAD. Overall, it’s the kind of game that doesn’t just entertain you for a moment, but actually gives you a consistently enjoyable experience every time you play.
