The reason why the control does not work for you is the wrong layout, for example, not English, but Japanese, Chinese, Russian, etc. It seems that the game reads not the button itself, but the input itself (I hope I managed to explain) simply put, squeeze {shift+alt} to change the layout and then everything will work
Another problem may be that the game section of the window was not 'selected'. This is more of a problem for people who navigate via keyboard in webpages, but should be resolved by downloading and running the game solo... or just click the game and try again?
Language issues can be worked around via language options. I use a japanese option, but type in (very bad) english at the press of two keys.
