This guide will go through all the levels in the game. If you don't know already, the rules state that no pregame is allowed and you must hit all the checkpoints. You can tell if you get a "ding" sound effect, or if the checkpoint is green.

Level 1= There are two ways of collecting the key. You can either jump on it or just run up to the counter. In the WR Speedrun, they use the 2nd way (running up to the counter). Otherwise, all you have to do is run up to the key door with the key in hand.

(I'll also be skipping levels that are really easy and no skips and shortcuts can be made.)

Level 3: There is actually a time save for this one. Instead of jumping across the teeth, you can literally jump on and off the red liquid that usually kills you. You just can't stay on there for too long though, or else you die. It's not classified as a glitch, because it is in the WR speedrun for this game.

Level 5: This is one of those levels where there is a black screen that fades in and out. Don't let this trick you, because you get teleported to the level first, and then the black screen goes away. You can tell if the level has started yet based on the checkpoint sound, or if you see it on the very top of the screen. Otherwise just jump past the toothbrushes.

Level 6: You can actually jump over a few parts of the water. One in particular is the small puddle near the middle of the room. With a well timed jump you can get past it.

Level 7: For the first part of this stage, just walk and jump over the blue toothbrush. However for the 2nd row of toothbrushes, there is a big hole with purple liquid coming out. You can jump on the purple liquid dripping down (not the liquid on the floor) to skip the 2nd toothbrush that you have to jump on. Since you get to the door faster, it saves a bit of time.

Level 8: It is recommended you use shift lock or first person mode for this one. You have to go through the top right door (the one with the glass that you can see through) and push this red button. Then you have to turn over to another door (this is why shift lock or first person mode is needed, to turn fast) and then you can complete the level.

Level 9: Walk right next to the wall near your left and jump over any teeth in the way, then go through the double door with the blue windows. However, once you touch the door, turn your camera 90 O to the left (assuming your camera is facing the door.) This will come in handy for Level 10.

Level 10: This is another level where the black screen fades in and out. The reason why you do that is so that you can immediately go into the vent because your camera is angled the right way, therefore not wasting time switching it when the actual level comes. You need to go to a room with a green box, immediatly turn after collecting it, and putting it in this hole in the wall. After that you go out of the vent and you're able to traverse to the next level.

Level 11: This is one of the rather easy ones, however you can skip a few boxes, in particular the first one, and the last one. Don't let the door at the end trick you though, because you need to go through a vent on the right instead.

Level 12: Touch the second door on the left. However once you touch it, just like in Level 9, you have to switch your camera angle. Once again, it's 90 O to the left, assuming you're facing the door forward.

Level 13: Just jump through the checkered pattern. The camera angle switch helps you get started on it quicker.

Level 14: On the way to the dentist, you can skip one of the box-shaped platforms on the corner. After that you just have to go into the dentist' mouth. However right before the black screen pops up switch your camera angle 90 O to the right this time (assuming you're facing forward at the dentist.)

Level 15: It's really easy, just make sure you had the camera angle right.

Level 16: Just walk through the moving killbricks, however you may have to jump once you get to the 3rd one.

Level 17: Just jump in a straight line in the middle. Like Level 3, the liquid at the bottom doesn't kill you for some reason.

Level 18: Once you get to the ladder, use shift lock and face right from the ladder. Go inside the middle of the ladder and spam the jump button, it will climb you up faster than it would if you climbed it normally.

Level 19: Try to jump only 2 times, because when you jump, you're off the conveyor belt, making you go slower.

Level 20: Get to the checkpoint and stop the timer, you've completed the speedrun!

Thank you for reading and I hope I helped anyone if they want to get into speedrunning this game.
