I am sorry for the inconvenience
We were low on times one of our members fell sick in the last week and we couldn't add some features that we wanted to add. This includes the instructions that you stated.
In the game's description, you can find a list of controls so do not forget to check it before playing as the game is automatically running in fullscreen and you will not be able to see the controls once you start the game
