Basically, What if you did an undertale run but with varrying corruptions?

This is something you'd probably want to discuss with the Undertale community.

You can find their discord server here https://www.speedrun.com/undertale/thread/4hum8

The vast majority of corruptions are purely aesthetic in nature, thus it changes absolutely nothing about the run itself.

In the event that it DOES change how the run works, this is a modification to the game code itself, and would be variable depending on the corruption seed, thus a nightmare to standardise.

tl;dr I wouldn't count on the community taking this seriously.
