I had no problems with mouse and keyboard. But the store page lists full controller support, so that should work too. Try out what suits you best.

Either ways it's a nice little puzzle game. I can recommend it.

Is it WASD only or are the arrow keys also an option?
This is a dealbreaker for an AZERTY keyboard user like me.

They changed the game completely. New storytelling, new puzzles, new controls.
In the new standard version you only use the mouse point & click style, no keyboard at all.

But you can also access the original version of the game via game properties > betas.
In the old version you can only use wasd. The only thing you can change, is the way the wasd movement works. Either straight (horizontal and vertical) or diagonally.

So you basically can get two games for one.
