Can't Let Go is the sixth main level and represents a noticeable difficulty spike. Many players consider it the first truly challenging level in the main game, demanding precise movement with tighter cube jumps, faster transitions, and abrupt gravity shifts. The level combines gravity portal mechanics with dark, predominantly black and red backgrounds. The in-game name uses 'Cant Let Go' without an apostrophe because the game's font does not support apostrophes. Prior to Update 1.9, it was rated Harder before being reclassified as Hard.
