I made this game counter: https://mikesgames.neocities.org/Games/Cursor%20Counter/counter.html for my friends and I (I'm in middle school so it doesn't have to be perfect).
I want to have a feature where someone presses the key(cursor) the game grants the initiator 10,000 points (in my game its cursors).
I believe I will need JavaScript for this. I have a little cheat button like this-
<div class="button" onclick="cheat()"></div>
btw I'm using https://neocities.org
