Hi,
I just started this game and finished the first level. The next levels appear to be locked. How can I unlock them?

Thanks,
Eli

Hey Eli, several other players have run into similar issues and we thought we’d resolved it in a production push on Friday. Several quick questions:

  1. Had you played any of the levels before?
  2. What operating system and browser are you using?
