Some Useful things, Running and jumping IS faster, During the fade to black imbetween levels you can return to the menu and hit return to skip the fade to black and immediately load
Level 1 (Aprox time 30-40 seconds)
Right at the start you will want to run to the microwave and press the button to add 10 seconds to the timer and immediately start it, to your left you will see a tool to clean snow off of your car, you will need to quickly grab that and then run back to the living room to grab the present, after that you will run back to the microwave and you can stop the timer at any time after 6 seconds have passed to quickly open it and eat the pizza. afterwards you will need to run outside, this can be done by opening the door or jumping through the left-most window, jumping through the window will only save around 1 second so if you can't be bothered that's fair enough, my tactic for cleaning the car tends to be to circle around it to clean the outermost layer and the crouch to glitch under the car to clean the rest given that you won't have to move to reach all of the snow, going from the back of the car to the front so that when all the snow is clean you won't need to move your mouse to activate the load to the next level because it will already be on the "activate area"
Level 2 (Aprox time 3-4 mins)
As soon as you spawn in you will immediately want to run along the road until you come across a purple truck, get in the truck and go along the road untill you get to a house with a yellow sports car out front, ditch the truck, take the sports car and follow the road ,with a few very obvious shortcuts, until you reach the town where people spawn in, my current strategy is to find a rock (that rock is very obvious which it is if you watch my speedrun of the game) in front of that rock is a rock where NPC's will spawn even if you are right next to it, making it by far the fastest method for money in the second level, kill as many NPC's as you need with the snowballs until you have 50$ drive across the road that goes past the super market until you see a bar / gas station combo building, slow down a little bit and ram your car into the gas dipenser thing to insure that it's where you want it, run around the truck into the store and grab a can of gas off of the top shelf, get back into your vehicle, do a 180 degree turn and drive to where you started the level, fill up your car by holding the gas canister and pouring gass into the funnel in your car (the gas canister will always be just one down scroll from the default equiped item)
Level 3 ( Aprox time 1 mins 30 secs )
Once spawned in you will need to run to your right and up the stairs of the motel, go along the doors until you reach the 3rd along, that is yours, run to the bed and activate it, here were going to do what i call a "movement unlock" where you can press the escape key to activate the menu and then leave it so that your locked movement is no longer locked and you can aline yourself with the next door along to the left at the motel, spam the "E" key and once your vision returns run to your bed and repeat the process, on the third wake up you will NEED to wait for your vision to be restored before opening the door otherwise the man you need to kill will NOT spawn in, so once you have opened to door and kill him run back to bed and sleep normally this time, because doing a movement unlock can cause the police to load in slower, once you have woken up leave your room as quickly as posible so that the trigger to load the next level starts
Level 4 (Aprox time 10 secs)
Upon waking up in prison turn to your right and crouch in the corner next to the sink, look towards the sink and the wall and crouch and stand back up again while walking into it and you will glitch through it (i call this the prison skip) , run through the tunnel (Do NOT run back as it will re-trigger the fade to black and slow you down)
Level 5 (Aprox time 30 - 40 secs)
Turn towards the road and then turn slightly to the right and cut through the edge of the forest straight towards to man you will ask for a ride to the city, upon quickly finishing his dialogue, get in the car and level 5 is done
Level 6 (Aprox time anywhere between 1:30 and like 5 mins)
This level is just kill everything in sight until you get $120 to pay for a taxi, the current strategy to complete this level as quickly as possible is to run around the city and urinate on people, because that can cause the AI's "fight or flight" response, you can tell if they're fighting you or running away because if they scream they're running away once you think you have enough people following you, head to the cars near the taxi and crouch under one of them, all of the AI running into the car is as far as we know the most efficient way to kill the AI, you will also want to be slapping them at the same time, once you have 120$ make your way to the taxi and finish the level
Level 7 (Aprox time 40 secs)
Apon starting immediately run to the right and get in the light blue truck drive straight forwards across the bridge and then go diagonaly (to the right) towards the red wooden house at the end of a little "cul de sac" looking place, if you get out of the truck at the right time and angle you will be on top of a little bush that will allow you to jump over a fence (during this time you should switch hold items to the present in your inventory) , once at the house go the it's window on the right and jump halfway through it and the jump and uncrouch at the same time, this will glitch you into his room where you will be looking right at him and press "E" to finish the run
