bruh i never expected this game to be on src like woah can someone tell me some tricks and stuff ( i was actually trying to speedrun this game a while back) so im hyped to see it here so yea Wooo!

Welp the only real trick I'd know of is the 1-7 Wall glitch, the rest is practice, doing levels over and over again, watching good runs helps too!

You can sort of hover in the air by mashing jumping + switch with a movable block. I haven't seen anyone do it in any runs but I can easily improve some ILs by using it myself.

Hey, I can't seem to replicate this. Do you have a video?

This should be a big time save once a proper route is figured out: I'm mostly just mashing jump and switch at the same time but changing the timing of the first switch slightly to gain more height.
