Sorry about the controls in 1.0.4. We changed the way things stick together, and building piles got harder instead of easier. Most of that is rolled back now, and the parts people disagree about have moved into the settings, so you can set them the way your hands like. From here on we'll be more careful with control changes, and when there's a call to make, it goes into the settings rather than getting decided for you.
A Controls tab in the settings, with three things you can now choose yourself.

If something still feels wrong, or you want an option that isn't there yet, write it in the comments. Getting controls to suit everyone at once is the hardest part of this game for us, and hearing what bothers you beats deciding on our own.
If Steam hasn't picked the update up yet, restart it, or switch it to offline mode and back.
