Yes, you have the option to reset your progress if you wish to start over. To do so, simply find the Reset Progress option on the Settings tab.

Please note that resetting your progress will erase all completed levels, and your game will return to the very beginning. If you simply want to revisit specific levels without starting over entirely, you can do so by selecting the desired levels by entering the lighthouse.

If you are in the middle of a chapter, you can leave the chapter from the menu screen and it will return you to the lighthouse.
