Oh no. I'm sorry you had trouble with the controls!
The trick is releasing the mouse button sooner, while the mouse is moving quickly, to fling the objects with some speed. Our fault for not making that more clear in the tutorial.
You're not alone. Dalton pointed out that the carbon-attractor-gun should have a more limited range, to enforce "flinging" instead of "placing".
Thanks again for playing!
