Inspired by OrangeKnife's Celeste corrupter and the Real Time Corrupter by CorruptedBytes, it's the Real Time Celester! A hack for Celeste that corrupts the game in real time as you play. Can you beat it before the game implodes upon itself? Post your times and your discoveries below!

Q: How is this different from the original Celeste corrupter?
A: Instead of using a fixed seed for the corruptions, the realtime corrupter randomly blasts corruption every certain amount of frames. This way the game get's more hectic and crazy as it goes along.

Q: How does it work?
A: The two settings on the main menu control the amount of frames per corruption blast (Frametime), and how many bytes to corrupt per frametime (Amount). It does this using the poke function, which allows you to change any byte of the program loaded into memory while it's running. It basically just uses that function coupled with a random number everytime it wants to corrupt another byte.

Q: Could you theoretically corrupt the corrupter?
A: There's a chance, albeit slim, and if it happens, god help us all.

I beat it in 3:25 with 8 deaths! I was really scared of it crashing lol.

I made it past about a third of the game, when Madeline/controlled character was gone on the start of the next level, so I guess I could say the run's dead.

Edit: I played again and there were two Madelines, which made the game problematic.

Challenge difficulty: Normal
Review: A new taste for an old dish, Realtime corruptor for celeste adds lots of possibilities for new fun.

I finished the game in 0:25 seconds, due to the spawning of a flag at 500m, with no deaths and 2 strawberries. The flag's a new one for me.

How would corrupting the corruptor happen ??
I thought peek and poke couldn't touch any Lua variables.

P#70266 2019-11-27 04:46

0 deaths

0 strawberries

10 seconds

It's really handy when the spring turns into the summit flag

P#71301 2019-12-22 06:12

I keep getting soft-locked with no Madeline.

P#73475 2020-02-26 15:27

Wait it can entirely remove the effects of the controls?

P#73484 2020-02-26 16:47

@oueoiiaoo yes i realize now that i have been silly :P

P#80699 2020-08-13 03:03

Welp I got softlocked shortly after getting green hair because the madaline spawn was overwritten.
was fun though :)

P#92148 2021-05-18 15:44

P#92210 2021-05-20 02:58

I got a random one where I got 44 seconds because the flag moved

P#92370 2021-05-22 16:51

it looks so cool when you put the frame speed to one and the corruption to 1000

P#92372 2021-05-22 16:56

no idea what time i even got but the "regain dash" sound was playing constantly in the final ~2 minutes and summit flag spawned out of nowhere

P#95997 2021-08-14 15:25

I made it to the final level in world 3 and then i got soft locked :(
Edit: I managed to do it without softlocking!!!

P#98709 2021-10-15 20:00 ( Edited 2021-10-15 20:09)

it corrupted and made a very off megalovania lol

P#111204 2022-05-02 16:50

set frametime to 1, and amount to something triple digit and up, it's a rave.

P#111984 2022-05-18 11:40

hey @AdamMcKibben

i was wondering if you were okay with me taking the corrupter part from here and putting it into a celeste procedural generator. just wanted to make sure if your okay with that.

P#124478 2023-01-17 21:45

P#130068 2023-05-23 15:56

P#134567 2023-09-19 00:00

The game just said No to me making prgress. Really fun mod 10/10

P#135349 2023-10-03 15:07 ( Edited 2023-10-03 15:10)

Ok this is realy fun but could you maybe try to remove the invisible walls it gets kinda annoying when I have to remmeber where like 70 different invisible blocks are to make progress.

P#135666 2023-10-09 14:32

Does this count as completing the game because I did it.

P#135994 2023-10-16 20:32

50 amount 120 frametime and the Mountain looks like theres about to an Avalanche.

P#136018 2023-10-17 14:30
