Sorry to bother you, but would it be possible for you to click on the ‘enable fullscreen button’ in the ‘edit page’ menu for your game and/or produce a desktop build for your game?
I’m encountering a slight issue playing the game on my browser (the viewport is a bit too big to fit in the browser window, and the scrollbars that appear in the viewport are less than ideal), but if you were to click on the ‘enable fullscreen button’ in the ‘edit game’ menu for your game, it might make it a bit more accessible. And/or edit the setting for the game viewport size in the ‘edit game’ menu so the game viewport won’t have any scrollbars appearing inside it.
Anywho, interesting way of factoring in the modifier.
