How do I move a game piece (atom)?
To move a game piece (atom) use your mouse cursor to click on it. At this time the available directional icon will become visible.

Can I use the keyboard to control the pieces (atoms)?

When I move a piece (atom) it goes right past the place where I want it. How do I make it stop there?
You don't. Once an atom begins moving, it will not stop until it meets either a wall or another piece.
I cannot beat the level. Is there a hint system, or a solver?
No. Unfortunately at this time KAtomic does not feature a hint system. So the only way to finish a level is to solve it on your own.
