Hey, thanks for checking it out! What browser are you running this on? It seems to work as expected on Chrome. Also, if your cursor is outside of the game window, your input won't be detected.
That was Brave Browser on Windows. That being said, the iframe used on itch.io does often make problems, in that the game canvas may lose focus and be unable to regain it, despite being clicked, unless you specificly canvas.focus() it in code after a click, as well as set the tab index to zero..
