worldline 000 is a puzzle platformer in which time rewinds after 10 seconds or when you die, but your previous actions are saved and replayed on subsequent attempts at a level. Your parallel selves can be a great tool to help you progress, but be warned that they can also make life difficult if your actions aren't planned out well. (And also because I failed to make physics deterministic, my bad.)

Note that the game is playable in browser, but it generally performs better and is less buggy on PC.

Known issues:
- Parallel selves are often desynced from the player's previous actions
- The WebGL version sometimes causes player to be yeeted in a direction when jumping onto a box, try downloading the PC version if this is happening to you
- Certain boxes do not trigger player pushing animation when pushed
- Player can sometimes be stuck in falling state on box corners
- Final rewind sometimes ends on a non-zero number if the player has died/rewound too many times
- Portals rarely teleport player to unexpected locations
