JumpLab is a software that allows you to experiment with variable parameters for jumping and camera movement in platform games (jump action games) such as Super Mario Bros. It is designed as an educational tool for learning how parameter settings affect the sense of playing in video games.
When the system reads an older version of the user settings file, the new parameters newly introduced in the newer version will have the same default values as written in Style.pde, but if a style with the same name exists in the default settings file, it should be set to the values in it.
