As many of you know, there´s is a bug with the refresh rate of the monitor, which increase the fps/speed of the game, and, theres people are doing runs using this "trick". i suggest to split the 2 main categories in "Glitchless" and "Glitched". This is because not everyone have a monitor with 144hz or 120hz either, and it´s unfair for those people.
This bug has already been banned and it probably won't be accepted as a category because of the way it messes with the game.
I don't think you can realistically call a game running faster due to monitor refresh rate a "glitch".
About a month ago, there was a community poll held in the discord to add IGT to Deltarune. After a close poll of about 70 to 5, we have added the use of IGT to the game. This IGT only makes a difference to the All Chapters categories, removing the time spent switching between chapter 1 and chapter 2
