Kye is a real time puzzle game. Some puzzle games, like Sokoban, work around a very simple idea, an extremely limited set of objects and rules - Kye does not follow this approach, because it contains a variety of different object types and these interact is a variety of ways. It takes ideas from puzzle games like Sokoban and Crystal Mines, but the inclusion of active objects gives it a real time component, and it can also produce arcade-game levels like Pac-Man.
