You should really just include SDL2.dll with the game download, nobody's going to go out of their way to find that on the internet just to play a game with no description and a screenshot that's nothing but blue.
I'm sorry to say this, but I tested your game (I downloaded the .dll) and I think this game is "much too simple" to deserve being posted on the LD... And you REALLY had to include the SDL2.dll in the game's download.
But, I sure hope you have learned some coding by doing this project! Keep practicing, and you will sure create better games next time! =)
