Play movie button doesn't seem to do anything when clicked. Who will think pressing space will play the movie?

Video doesn't play. Only can see the first frame. Tried in a second browser and same problem. Update: didn't work in chrome but worked in firefox.

I walked off the screen in the top left then nothing happens. The guy doesn't seem to come back. Tried a second time and it seems fine

Not sure how to play this game. I click the multiplayer button it says 'P1 wins' but the win one game medal doesn't unlock. Need to add instructions
