on some levels, i've experienced a glitch where you teleport straight to the portal after hitting the button. so far (iirc) i've only had it happen on levels 5, 9, 12, and 17. i've hit it like 3-5 times on these levels and never on any others. i have no clue why it happens but i theorize that it may have something to do with changing your direction or speed as you hit the button? if we could replicate this setup consistently, it would save a bunch of time, especially if we can make it happen on more levels. i made an image of all the level maps for reference (sorry it's a bit ugly LOL)

I've just had it happen on my stream I'd have to check the vod to see what level, but I also had it happen while I wasn't recording on 11.

after some testing i think the glitch works something like this:

you have to have enough speed, and the portal spawn has to be behind you. if you land onto the button with enough speed and tap the opposite direction (to face the portal) right before you hit the button, you can teleport to the portal. i got it to work pretty consistently on level 17 and even got it in a run, but on other levels i haven't had much luck yet, which i think is because it's hard to build up the speed. worth testing on other levels for more timesaves!
