Hello and welcome!
This will be, as always with me, a concise and no spoilers walkthrough to guide you through the game while getting 100% completion.

The game itself is pretty short, easy and only has a few missable achievements but since I love this series so much- and have already covered a few games from it- here we go!

After a scene you'll be in control of Phil, interact with the flashing phone, click confirm and then hit the "leave" prompt when it appears at the bottom of the screen.

You'll now have four different options and you can tackle them in whatever order you wish, here's what needs to be done for each.

EAT; click the closet on the right, choose tomato soup, noodles or beef then click on the cooking pot at the bottom. Clean up once done.

PEE: click the closet on the right then the empty bottles on the middle shelf, click the closet again afterwards. After a scene look at the cardboard box to the left of the telescope and snatch some fishing line from it, go back. Click on the paper bin on the right side of the bed to get a plastic bag. Drag the fishing line on the bag then the bottles on the bag with fishing line. Use the resulting bag on the window. Click the trash can below then the bag itself. Choose any option during the dialogue to finish this section.

WARM MYSELF: click the heater next to the window then the top shelf to fnd a lighter, use it on the heater.

SOCIALIZE: click on the telescope to begin. Move right, past some crows and a dog, to spot two people, continue right to see a woman.

Once done simply click through the phone conversation and choose whatever dialogue options you wish.

Click "purchase food online" to get on your pc, here start by clicking the news app on the lower left to unlock the missable WORLD NEWS achievement.

Click the Hayashi Groceries icon and then "complete purchase", after the error message simply exit the computer for a few scenes.

You'll be in a conversation, as usual pick any options. Click the relatives to continue then your blinking phone and hit "confirm". You'll have a few scenes.

Another phone chat comes up, pick options and continue.

You'll wake up and watch some tv then move to your telescope, simply keep moving right.

Choose "talk to Piper" and go through the dialogue. Once the computer screen turns red click it.

The password is prospero and it's easily found on the last to bottom row. Now start the "puzzle inferno" game and drag the pieces to complete the picture. They make a sound and lock in when placed correctly.

Click the phone and confirm. Click the heater then the note, once done select "thank Piper" for a scene. When you use the telescope keep going right.
