Celeste - Breeze Contest - apartment complex in time - nuwut - Part 2

i love adventure games, but this is why i don't play adventure games. i'm on the fence about looking up a solution vs just giving up and being done with breeze contest. i don't want to deny myself the thrill of puzzling out some outrageous moon logic, but i also would like to play the heartside. here's where i stand.
crossing
i've got a bunch of numbers and a bunch of colors. there is a mapping between numbers and colors, but it's not a bijection (blue maps to 1 and 3). i have directions associated with some of the colors from the clock in the center of the map - 7 is down-right, 1 is up, white is left, 2 is up-left, and ! is right. there are a couple hints outside the map, a dash code in the level select card (which doesn't seem to do anything, though the last few directions are ambiguous due to the background) and the number 7 associated with the directions upleft, upright, right, and down. if i go to the matching car in the map and enter that specific sequence (other orders do nothing), then the broken image turns into a red square. i don't know what that means. 7 is yellow. there's a room with 4 numbers and 3 colors in it. there is a trail of arrows near the top of the map that doesn't seem to correspond to a dash code. in the room with the rainbow mirror, there is a clock showing 2 directions and there are 3 strings of 4, 5, and 5 lights. in another room there's a floating black foreground decal and a sign with an arrow on it that might give a direction for black. i couldn't find any other hints outside the map unless the 2 golden blocks are a hint of some kind (or the white arrows, but those don't seem to have an associated order). i considered that the level select dash code might indicate a room traversal order, but that seemed to require a larger area than 3x3 to fit. i don't know what parallel universes means - maybe it indicates that there are hints outside the map, or maybe it means that i can finish the map with half an a press. my best guess is that i need to fill out the mapping from directions to colors/numbers by entering different dash codes in different rooms, and then enter the dash code given by the long color sequence in the order given by the numbers (idk what to do about the missing 6, which maps to the center of the clock).
what is there
i've got a note that maps 4 random symbols to 4 other symbols by arrows. those 4 symbols seem to depict a gear, a whirlpool, and asterisk, and... something. there are also 4 numbered boxes along the ground. one of them lines up with a wheel, which could be interpreted as being the gear. the others don't seem to line up with anything - some of them contain water, one of them contains 4 stalks of grass, but i don't see any way to map them to the other symbols. even if i did, i don't know what i'd do with that. there's nothing mapping these to dashes (unless the arrows mapping symbols to symbols are also dash codes), and i'd have two different orderings to contend with (the ordering given by the note, and the ordering given by the squares). it doesn't seem possible to touch the number squares in any sequence other than left to right or right to left - i can't find any way to go around any of them.
trial by error
i have gathered that if i visit 6 locations and then return to the start of the map, that will cause me to teleport to another location. the new location contains a dash code that doesn't seem to do anything. i thought the dash code might instead indicate an order that you need to visit the 6 locations in the first part of the map, but the mapping from directions to rooms is ambiguous - the diagonals could be the corners, and the verticals could be the upper and lower middle rooms, but what about the horizontals? there are no middle left/right rooms. by pressing ctrl b i have also learned that there are triggers over some of the chained heart decals in the second part, but that hasn't clarified anything for me. maybe they also have to be touched in some order, but i don't see any way of figuring that out. from the map title, it seems plausible that you're meant to find a solution by guessing, but i don't even have a finite set to guess from.
broken house garden whatever
you can carry the dream dash into the next room to access both dash switches, but there are 2 more gates that need to be opened to get out with the pink refill, and neither of them is activated by the dash switches. also you can't activate the dash switches (or kevin) until after using the dream dash. there seem to be some pink markings on the contain decals in the lower left of the room, and some of them look like numbers and directions. i see 2, up, left, 3 or right, ?????, and down-right or 6. i have no idea what to make of these. i haven't been able to find a dash code interpretation that does anything. the chest and crate decals appear in a couple places elsewhere in the map. it looks like the kevin is sitting on some pink goo with the same color as the markings.
