Ok so theres a couple glitches/exploits that i have found. first and foremost, in some areas, it is possible to ledge grab a wall that appears to be past the top of the screen, allowing you to walk above the screen. if you do this right after the lamp after getting the wall cling thing, it saves you a few seconds.

second, the dash ability is a bit broken, and can be used to gain insane jump height. There are multiple ways to achieve this.

first way is to press dash and jump at the same time while walking off of a ledge. i think that the coyote frames allow for you to transfer dash momentum to jump momentum or something like that

in the up draft area, this adds an unbelievable amount of jump height

this ledge boost allows you to skip the ladder that leads to the endgame room.

another thing that is possible is to fast fall and dash at the same time into a mushroom, which gives you a bunch of height. heres a demonstration of using both mushroom jump and ledge boost for a possible 100% route (its a bit Un optimal but whatever):

So anyways yeah just wanted to share this with everyone. Idk if anyone will even use these since theres so few runners but yeah with these im pretty sure a sub 1:30 tas is possible for any%, and probably a sub 4:30 tas for 100%.
