The chapter selection map is the first map screen in the game, and the first screen the player sees whenever they start the game. This screen shows the planet on which the game takes place. From here, the player can select one of the six islands on the planet, each one of which contains a chapter. The goo balls on this screen are interactive, as the player can pick them up and throw them around. At first, they will only be able to select one of the islands (Chapter 1), but will unlock more as they progress though the game, culminating in the Epilogue. From this screen, one can also watch the credits or change save files (the game uses autosave).
