Is that a glitch? Yeah, I just need to know. Who doesn't knows, it means you open the inventory in that room, and Mauswheel gets really slow, and you can just walk thru, it can't get you. Now ya know a new strat. And about the name: I made it just now. Mods has to answer the question.
this is well known, documented, and most importantly not a glitch
its 100% unintended but its coded to slow down in that room if you open your menu, and its extremely silly to ban openning your menu for a specific room, so no ones going to ban it
also please for the love of christ use the discord to ask about strats or routing not many people look at the threads
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
