Note: While I am linking the original versions of the main story here, they are ultimately unnecessary to read unless anyone wants to know what the original versions were like. There is a rebooted version of Little Moments that has completed development and a reboot of Breaking Point is currently being worked on. The rebooted versions are the preferred versions to read as they are indeed vast improvements over the originals. Links to the rebooted versions are placed below.
