now this is going to be an explanation, rather than a full video of it, although i will be providing an example run from Rumba to see what your runs can look like. here's the explanation:

1. start off by grabbing the trashcan and place it on the fence so that it doesn't fall over. then, jump onto the trashcan and try to aim for the second plant.
2. after you have your sights on it, run and jump towards it and perform a crouch at about the apex of your jump, and after spam jumping to get on top of it, you should be on the roof.
3. from here, go towards the satellite thing and grab the crowbar; then, fall down onto the keycard, grab it, and break the window.
4. finally, jump off towards the ground, go around through the open bedroom window, and after entering the house, run towards the living room, and unlock the basement.
5. it can get laggy here, and from what we know, there's no way to improve it other than getting a good enough computer, but despite that, upon entering the basement, MAKE SURE to look straight and not down as you run faster while looking directly straight for some reason. this alone can save you like 2 seconds. and that's it! hopefully, alongside the example run, this will help you learn alpha 2. here's the example run and cya:
