The game was created for the project during the 4th semester of studies in computer science at the Silesian University of Technology. The time I spent on the project oscillated around 4 - 5 weeks.
My main knowledge comes from the documentation of individual libraries. In the process of learning (started some time ago) I also read two books: C++ Primer 5th edition and SFML Game Development. I also get a lot of help from the official SFML forum. There are many helpful threads there.
