I bet it got pulled from the store due to that Donald Duck image in their screen shots, Google doesn't mess around with copy-write. Hopefully they can get it back up and running on the play store soon.
@Daniel, you should upload a clean .APK to getgems.org, and verify the hash publicly so people know they're installing from a clean source.

Most Google searches include results that it says have been removed for copyright breaches. Google has to some down on copyright infringement like a ton of bricks or risk getting sued itself.
Got pulled from the store maybe due to that Donald Duck image in our screen shots, google play does not have a manual approval process, someone must have flagged our application.
We apologize and working to have it fixed asap.
You can use our direct download link to install for now:
