Wew this gets frantic quick, real fun! Glad that first comment here mentioned having to hold down space cause I also thought that was bugged til I read it. Will note that the control screen lets you click which turns that input into left mouse button, and you gotta go into the html to like get the source game because it saves the input change (and you can't change it back cause hovering over it and pressing any other button doesn't change it, it only changes when clicked) even though I tried clearing my cache/cookies, can confirm playing with moving right determined by lmb to be a terrible experience lol.
