Regretfully pointing to the arcade from your own website, your link is blocked by MalwareBytes because of a possible unwanted program (PUP).
While your game and website is perfectly valid, MalwareBytes seems to think the forward is suspicious.
I contacted MalwareBytes support several times about blocking perfect legal websites, but there are no willing to do something about it. However, a user can always exclude it from the quarantaine list. However, many surfers panic by seeing such a message.
I am no fan of Wix either. Too limited in my opinion.
