Pre-release material for UNBEATABLE showed that Beat's journal originally featured additional tabs containing a map, a song list, and a to-do list, the latter of which would track main events and sidequests via a diary that Beat would update as the player progressed. By 2025, the map tab was replaced with the items tab, and come the final release, the "Songs" and "To-Do" tabs would be excised altogether. Despite this, assets pertaining to the "To-Do" tab are still present in the game's files. The pages seen in the Day of the Devs 2021 trailer are almost entirely intact in the journal's object tree, albeit with slight modifications, while text for various other entries pertaining to Episode Three are present in the game's dialogue system.
