Hi, I tried to run the game with Steam but nothing happened, and when I try manually it says that I don't have the SDL2.dll, I think you need to add them to the build folder

This update includes the DLL files that it depends on. As the developer I have them in my path but forgot to include last time! So sorry about that!
