Remarks

<p>
    You may be tempted to use a variable-width font to see what it looks like. The game won't stop you from
    doing so, but you should have a first-aid kit ready for the inevitable and almost immediate typographical
    hell you will unleash on yourself and the surrounding planet. Seriously, do not even try. Why did we even
    bother exposing this fucking property?
