I am not sure. Does the character look like a pink-insh blob?
On the first level, I was instructed to just press W, and the blob did move to the right (which is a bit strange, in the usual WASD scheme I would expect that W moves character up). I did try to “choose direction” with mouse, but nothing changed.
On the second level, there was no pink blob on screen, and nothing moved at all no matter what I pressed.
