Did you try the Windows or the Web version (if you used the web version which browser)?
What are your PC specs?
Was the framerate low or did it look like an input problem?
If it seemed like an input problem and you played in Chrome, would you mind trying it in Firefox? I know of an input bug in Chrome which I managed to somewhat "fix" but maybe not for everyone.
originally tried it on Chrome on my work-mac
on firefox 56 (last true firefox IMHO) on my home-pc (win 7) it runs like a train
