About

Building Blocks Master

Features
Read full description

This is a building block app. It can be played safely by people of all ages, from young children to seniors. In particular, a sample is included by default so that it can be enjoyed as a block-breaking game. Of course, you can also enjoy using your own created building blocks as a block-breaking game. Main features are as follows: 1. There are 14 different building block shapes. 2. In addition to solid colors, you can choose from 14 different textures for the block surfaces. 3. An infinite number of solid colors can be set. 4. Blocks can be easily added up, down, left, right, and right. 5. Blocks can be added continuously with a long press tap gesture. 6. The shape and orientation of blocks can be changed later. 7. The size (length, width, and height) can be freely changed. 8. The surrounding (wall) colors can be selected from 10 options, including 6 realistic backgrounds and 4 solid colors, allowing you to enjoy a unique world view. 9. You can export your masterpiece as a PNG file via screenshot. 10. With the video creation mode, you can record and publish videos of your completed creations and the process of creating them. 11. Since gravity is not applied, you can set blocks while they are still in the air. 12. Since gravity can be applied later, you can have fun destroying your creations all at once and then recreating them. 13. With the block-breaking mode, you can enjoy it as a game. 14. With the AR mode, you can create and display creations in real space. This simple building block app fosters limitless creativity. We hope that users of all ages will enjoy it.
