Yes, there is an icon that follows the mouse cursor, we used it as a fire button, we thought it would make the work of the player easier. If we made the size a little bigger, it could have the effect we expected. As I understand it, there has been a misunderstanding. It is enough to crash the plants with character to eat, it does not require clicks.
We tried it in different browsers, since we developed the game directly with JavaScript, the development process was also on the browser. We did not have a problem with its loading and in the game, but there were notifications of problems. When the voting is over, we will discuss where there may be a mistake and what can be done. Thanks again for your warning.
