Hey so I was just playing with this and practicing strats to maybe run, and I noticed that the bubble trick doesn't actually work anymore. It might have been patched out in an update. Which now has me curious, is there any way to play the game without updates, or is my run doomed to be slow there forever?

Which section?

near beginning i think

What do u do and how do u do it

You jump under a platform and trigger a bubble which moves forwards instead of backwards due to misplaced bubble triggers

You may be having difficulty because you dont jump far enough before bubble useage
