Thanks for playing! Good score! Sadly I work with Game Maker and the online leaderboards have some issues, especially on HTML. I'm looking for alternate solutions so hopefully I can find a work around for the next jam we do.
I think the lag is due to too many objects on screen at once, I was getting it here and there, mostly with the hourglass pick up, but I've noticed that with webGL enabled, it lags HARD - I had to disable it to get it to run smoother in the browser.
