Please use full screen. This project works better on full screen mode. Press the green flag. Use the blocks to create structures. You can drag them. Click on them to change their colour. To make a new block, press the plus in the corner. To make structures in the air, make sure the upper blocks are touching the light blue on the bottom of the screen and the top of the blocks.
