Hey, I decided to go around and find new cube jumps. Most of them are small timesaves, but some are pretty relevant - a bunch of them I haven't timed yet, so I'm not positive they save time, but they are at least comparable.

Labyrinth + C1 Star: Oubliette + Star: Friendly Crossfire, Things to Do With Two Boxes, Stars: B7 Star: Me, Myself and Our Two Jammers:

Ask any questions about the lineups if you can't get those jumps in game, but keep in mind I get most of them on 64 FPS because of how FPS oscillates even at fixed framerates, so if you have a different framerate you might want to look for some different pixels.

Multiply Impossible Ascension has an even better cube jump from Blowback, it's updated in the main post.

Updated Labyrinth + C1 Star to reflect new discoveries about player speed & cube jumps; happens to chain with MIA well.

Updated with Unreachable Garden ¤NEW¤ cube jump and moved C1 from 'possible' to 'good' timesaves since it is indeed a good timesave

Updated with a much more consistent Oubliette jump, removed outdated CJs / slower CJs.
