How to make a Celeste map 1000x harder. (Ft. NCG)

This achievement is historic and has been done with ‪@NCG337‬ .
We have a Discord server with a couple Theo enjoyers where we are looking for interesting and hard Theo challenges.
The 1st challenge that I have started since a while, consists of trying to beat all the Vanilla with Theo. Here is a Google Docs with all what have been done : docs.google.co...
Except a couple impossible or too hard rooms, everything has been done.
For instance I have achieved prologue, 1AFCG, 1A Dashless, 1B, 1C, 2AFC, 2AG, 2B, 2C, 3AFC, 3AG, 3B, 3C, 4AFC, 4B, 4C, 5B (except 2 rooms), 6AFC, 6B, 6C, 7A (except impossible ones), 7B (except impossible ones), 7C (except the impossible orb), 8AFC, 8B (except the impossible orb), and Farewell at 96%, all of this with Theo.
‪@NCG337‬ also got 8AG with Theo, ‪@theepiccarrot7‬ got 4AG with Theo, and a few ones have done 1A Dashless with Theo golden. Shoutouts to them !!
But, we never have been able to say if 5C was possible with Theo, especially because of the last room, and mostly because of the long spinner corridor. This section is particularly insane because Theo can't stay on spinners, he' necessarily ejected at left or right, with 75% of chance to go at right, but 25% to go at left. If he goes at left only once before the end of the corridor, you can restart. It's not luck, but it requires a real precision on the x position (0.25px precise) and y (because the bonk on the ceiling is important). Even if Theo reaches long enough in this corridor, the spinner unloading can break everyhting and theo can go more at left ! All of this after 15s of very precise and advanced Theo gameplay lol
But the October 6th, we have found a way to beat this corridor, and then, the whole room !
NCG and me have started the training and the attempts the 11th, and we have cleared it randomly 10min apart !
Extreme shoutout again to ‪@NCG337‬ who finally goldened 5C with Theo 1h later !!! (his strats are better than mine tbh, by far) Just awesome !

[@NCG337]

I still cannot believe we beat it 10 minutes apart. Nor that I goldened it. Like excuse me. what. In under a week we managed to completely destroy the ONE level that's been teetering on that edge between possible and impossible for over 9 months now. With the grim state of 5A this might be the last one to be confirmed 100% possible and with that, this is the end of an era and I'm more than happy to have taken part in it!! We never say never here tho, so let's hope to beat those last few impossible rooms!!

Celeste Theo challenge huh?

[@typorium]

Theo's been in his crystal for years and somehow still is in mirror temple...

[@CHAZZRMAN]

I can just imagine you sweating as theo just boings back and forth like some sort of extraterrestrial dance

[@ZKBceleste]

[@Wolf_Zero]

What. Absolutely mind blowing

[@BulleTRiP]

This is absolutely incredible. I can barely imagine the amount of brain power you guys managed to output for both theorycrafting this and mastering the execution. A beautiful testament to your dedication to this amazing game, the devs must be so proud and happy. Mad respect.

[@dectoriscool]

this is so real, this is SO FUCKING REAL GG's to you two!!!

[@DesTr069]

[@Talking__Ben]

Max% with theo when

[@ZKBceleste]

It's almost done

[@tabarak_allah_subhanah]

WTH THIS IS INSANE

[@tiddly5]

awesome job!! is theo bouncing the only actual gameplay element with rng? i thought everything else was consistent

[@ZKBceleste]

It's not rng while spinners are placed with regular spacing. I theorycrafted the probabilities when 1 spinner is placed 1 tiles over 2. Basically, you have 75% of chance that Theo goes in the direction where you threw him. 25% the other one. Because theo goes in the wrong direction if he's at the left of a spinner, without touching the other spinner. It happens 4 pixels over 16. Each time that Theo is ejected, he moves by ~16,75px, which means that there is a littly probability that his position on the next spinner doesn't work. It's also very interesting because Theo can't mathematically go through more than 21 spinners. 21 is the maximum. And here you need to get 12 with my strats, 13 for NCG's one. And with the actual position, which is really restrictive, the subpx allow to get 13 spinners maximum. We are so lucky wow. Nevertheless, the tech is a bit rng because the spinner unload can for some reason force theo to come left back, which is absolutely what we don't want ! That's why in my strat post-corridor, I need to start my moves at some very precise moments. I think you now know everything !

[@tiddly5]

@@ZKBceleste i see! so not actual rng, but effectively works out that way

[@mrploplavraie7376]

non

[@nadagx]

first of all, wtf. second, how many deaths do you have in all the theo challenge runs total ? third, congrats 🎉

[@ZKBceleste]

I have absolutely no clue about how many death I got during the challenge ahah. I can just tell that it should've take me like 150h among the 1000h+ I have only playing with Theo ;)

[@nadagx]

thats a lot

[@moncef2733]

What

[@xminty77]

wtf
