Gee the leader board is such a good idea for replay value. I couldn't quite make the top 10 though!
I had trouble at times see which player I was at times, particularly after a dash. In the end my best strategy was running in circle to avoid the mob. And hopefully get them knocked out by the train, super satisfying!
I did encounter a but that once I played fullscreen no controls worked and I had to reload the website. In the end I just played non-fullscreen.
