Show HN: Interactive Website I did (magnovite.herokuapp.com)

I also had no idea how to play initially because my mouse was over the game area and so the how to play instructions disappeared before I could read them.

Yes you are right. The website is meant as a landing page for an event. But yeah, I should make the game mode more obvious and straight forward to get to.

Actually I dont know about a library, I got the idea and the core code for the effect from http://lamberta.github.io/html5-animation/
