Hey, been routing this game independently for a few days now and wanted to point out a glitch after the umbrella room. Using the down+up trick and holding right doubles your speed until the end of the room only for some reason. Looking forward to doing runs and would love to participate in the community if there's a group somewhere.

This is the 2D/Sidescroller room right? If so I noticed it was before and was really interesting.

We'll need to start centralizing all the discussion because we've already discovered this over on the SDA thread: https://forum.speeddemosarchive.com/post/undertale.html

I've made a sticky thread for future reference. We're still not quite sure why this room gives us double speed though... Any possible thoughts? :P
