I started this map back in September of last year, when each mapper was given their prompt. I was really struggling to come up with any solid idea, but after playing perlinue's own map (Singularity Station) it started coming together. Initially I was definitely trying a little too hard to adhere to the prompt I was given (see below). I ended up really sticking to "input dense optimization," "tight timers," "one kind of moving block," and "gravity helper." Sorta wish I didn't go off the deep end in the "don't rely on [buffers] too much " part, but at least it's really only prevalent in the second half of the map 😭
By Christmas, my map was in a giftable state, however I really wanted to do the gravity helper part justice and had a really good idea (these were the gravity helper fields). I finally finished and deco'd the full map in February, and I'm quite happy with how it turned out.

If it's not clear, the deco was inspired by various sasakure.UK MV's, specifically "the EmpErroR," "Helix of Garatia," and the cover art from his album "トンデモ未来空奏図." Huge thanks to EvanKrusher for providing the tilesets and a few decals. I'm really happy I was able to get the colorgrade masks working (the red and brown areas) and especially the gravity reverse fields (yellow areas). The map isn't very deco heavy, but these masks fill empty space so well while also looking pretty sick. Also, this map used to be called "Helix of Garatia," based off the song used in the map and the MV. After extending the map and introducing the gravity reverse fields, I combined the map name with "Atropos," which is the song used in the second half of the map.

Gameplay-wise, I cannot thank my playtesters enough. This definitely would be a lot less enjoyable if it weren't for hyper, dragonned, Paz, monitor, and perilune (yes the receiver of the map). The gameplay isn't perfect, there's still a few spots I might go back and make "less bad" but with what fixes / edits I've already made (and how long they usually take), I'm content with where the map currently is. Also really happy I was able to come up with pretty unique ideas for each room.

Hope you enjoy and good luck! This is probably the hardest map in the collab!
Also expect to see a full hard lobby video within the next week or two

Prompt:
"Input dense optimization gameplay with tight timers, like Geodesic/heaven rush, but with heavier entity use and a more structured route. Buffers are welcome, but don't rely on them too much as it takes away the point of the timer. Try to use timers that are more creative than switch gates. Good example is probably FR-C2, but maybe with a tighter timer and more focus on optimization.
Gameplay itself should be fair and not extremely precise, and try to include some less common tech like momentum carries or crumble/falling block tech. Light routing is appreciated but should not be overly confusing.
Use gravity helper liberally and creatively, especially things like switching gravity mid-dash or mid-tech.
Other gimmicks (throwables, grapple, ceiling ultra etc) are acceptable but don't make them the main focus of the map.
Any entity palette is fine though I'd like at least one kind of moving block.
Difficulty should be somewhere between red expert to green GM+1, though I can play up to red GM+1 if needed.
For environment and atmosphere, really anything is fine, absolutely focus on gameplay first.
Bonus points if it includes any of the following: stamina, dash/jump/grab-toggled entities, cassette blocks, low friction, badeline chaser
Finally, don't stress too much about adhering to the prompt too closely! Just make some fun gameplay that you think would fit the prompt in spirit. And don't overwork yourself! I'll be happy with as few as 5 rooms."
