Play From Zero (PFZ) is a developmen concept that states that, from the moment you start a work session till the moment you finish, you need to make a new game. You can use that game to make another different game later, but you must always leave a new and usable result.
Play From Zero #1: Boosts'n'Baddies is a very simple dungeon crawl. Find boosts (brown) until you feel ready to take down baddies (green) as you explore the dungeon. Different experiences can be created by modding the stup file, which includes (in order) X and Y size of the dungeon, zoom (bigger means more dungeon is visible), number of content (half boosts, half baddies), and movement speed. Enjoy!
