I’ve made a simple arcade game purely in Java (without any 3rd-party libraries). Images are painted with gouache. JDK version 8 and an analogue of Notepad (Akelpad) were used 
Plot:
Julia is sitting at home and thinking about Willy, who works at the North Pole and has to stay here, and isn’t able to visit the girl at Christmas. She decides to go to the office of Santa’s employees and ask Santa for help getting to Willy quickly.
