Regions is an abstract, minimal puzzle game about drawing paths and understanding geometry. The 6 x 6 playing field is divided into different regions and your task is to draw a path that covers only one square of each. Later levels introduce regions that have different mechanics to keep things interesting across 160 levels. Regions also features a dynamic soundtrack that responds to how you play. Also included is a level editor that unlocks after the entirety of the game is completed (or when a secret code is entered). It isn't a fully polished product, but it's in the game for those who want to mess around with the same tools that were used to make the game. A color blind option is also available. Update: As of March 17th, 2020, this game is now free.
To reach your goal, you must change yourself. This game can be difficult, but the difficulty curve dips down every time a new mechanic is introduced. If you get stuck, don't be afraid to skip ahead - there is no penalty for doing so! Progress is saved as long as you have third-party cookies enabled.
