A and D (or cursor keys left and right) rotate the selected shape. Use mouse for the rest.
NOTE! If the game won't load, disable adBlock as it seems to break the loader. Thanks! And sorry about that, I don't know why that happens on some computers. I don't have all the browsers or operating systems here on my computer...
NEWS: Added mute button to game screen, and quality button to title screen. Tiny angular and linear velocities are now damped, and you cannot drop the shape you are moving if the mouse pointer is also on top of another shape (meaning less room for exploits - you people wanted this via bug reports). ;) And now the game has a very small air resistance as well.
NEWS2: The addition of air resistance broke two levels, E-8 and E-16, please wait until the fix gets updated to this page.
NEWS3: Added button for turning autohiding of mouse cursor on/off for greater accuracy.
