Depends if they do web searches and actively persue such a thing. Also "fan" games are often tolerated, it depends n the company. I've never got any emails about my free Tetroid game. Anyway, changing the name (and maybe the look of the cards if they are too similar) could be OK. But I'm not an expert in these areas. You can always leave it is and wait for any contact and then change because perhaps you'll never be contacted. Some I think people can be over paranoid in life, and sometimes you've just got to get on with it...
I just played it and it's cool, very nice to see the framework used nicely for a proper complete game, well done!
