Finding inspiration from other games

In April this year I participated in the Ludum Dare competition where you are making a game in 48 hours. I made an Aircraft Carrier Simulator, looking like this:



Today, I saw on steam that someone had released a game called Carrier Deck. It looks like this:


In the game you "manage the deck of the Nimitz-class nuclear powered supercarrier, the USS Ronald Regan (CVN-76)." So the game has the same game play, the same view angle, the same carrier type, and the same F18 aircraft as my Ludum Dare game had. I wonder if they found inspiration from my game? That would be cool because I don't mind anyone finding inspiration from my ideas. I had plans to make a complete game out of my Ludum Dare game but decided not to because I thought it wasn't fun enough.
