Unfortunately the new owner took over a domain name that had a bad reputation.
Now it is just a simple little game without a lot of reasons to throw red flags.
Perhaps the only flaw is the social media pressure- which would mean privacy issues. Other than that there are no apparent issues.
The review and negative score from 2013 has nothing to do with this site. This is a newly registered domain, registered in December 2014 for the sole purpose of hosting a web game called Circle Push.
