Press the green flag to start. Wait for the sprite to finish cloning itself. Press space to change the 3d shape Use the left and right arrow keys to look at the cuboid from different angles. Use up and down arrow keys to move it around. You need to press space twice to change the cuboid( I'm not really sure why).
I made this by cloning the sprite multiple times and then made all the clones rotate when you press the left or right arrow key. Sorry if there are a few glitches.
