First and foremost, we have a level editor. You can get at this by pressing ctrl-e anywhere in the game, and it’ll start editing the current level. The level editor will edit our levels in place, overwriting the core content in the game; thus, you’ll find any new levels you make inside the game data files, under ~/data/levels/. On windows/linux, the data folder is in the same folder as the .exe, whereas on mac, the data folder is inside the program icon; you can get at it by right-clicking on the icon, selecting Show Package Contents, and looking inside Content/Resources. (Naturally, everything else for the game, such as images and music, are in nearly the same place.)
