What do you do when you find a game very similar to yours?

What is your game? What is theirs?

I am curious because I am thinking, "Is it really all that similar?"

As a developer of the game, you might be more sensitive to worry over these types of things, and it could be helpful to get a perspective from others.

What if, to us, the games are very different? Then you have nothing to worry about

What we think is usually different than what other people perceive. Like when we hear our own voice and think "Eww!" or look at ourselves in the mirror, poking our eyeball, thinking "I am a sack of meat? *poke poke* Is this really me? *poke poke*" LOL
