Initially, Stickman Hook levels are quite easy to get used to. But as you progress, the difficulty will gradually increase – requiring a combination of reflexes, judgment and the ability to handle situations quickly. Some levels require you to hook at almost perfect times, or to perform consecutive swings without a break.
Each time you complete a level, you will feel very "satisfied" because you have just overcome a worthy challenge. That makes players easily get hooked, always wanting to try "just one more level".
