Skala is a game about changing the physical scale of things. You can make yourself large enough to step over a giant cliff, or make a key small enough to be passed through a solid wall. The game explores the consequences of this rescaling mechanic through simple yet difficult puzzles.
There are over 90 puzzle levels to play through. Every level is unique and has some purpose, whether it's introducing a new idea/mechanic, or developing on the concepts of previous levels.
