Every chapter has its own puzzles, ranging from 1 to 39 chapters (40th chapter is a final scene, but no traps, obstacles and enemies). Respectively, it progresses from easiest to hardest. Chapters can be called checkpoints; they are automatically saved when a player finishes each to proceed across the continuous side-scrolling path.
