Maybe you heard about this game a while before you made yours, but just don't remember it. I read an article about how the brain works and it mentioned that you can forget about things you saw or heard about before, but it sits in your subconscious, and emerges as what you believe is an original idea.
Or just a horrible coincidence lol. :P

Lol that's what you get for accusing so readily, just accept it was an unoriginal idea.
Sorry :(

I guess there are no original ideas in games anymore.
