[SPOILER] Having trouble with the ending

[Douota]

I'm at the end of the game, after I've found the photos of myself and closed up the shop.
I've run around the coffee shop after flipping the "Open" sign, but I have no idea what to do from here.

After flipping the sign, I:
Got the ladder and climbed up to the roof > Got the brick from the roof
Went back to the stalker's hideout > Got the screwdriver
Ran to the bathroom > Unscrewed the screws on the grate and got outside the shop
Picked up the car key on the ground outside the coffee shop.

From here, I'm not sure what to do. I'm stuck with the screwdriver, brick, and key (and the video tapes and cleaning items, but those don't seem useful) but can't seem to interact with anything. Can't open the bathroom door anymore, nothing in the hideout appears to be interactive besides the photos. I assume my next goal is to find my cell phone, but I can't find it anywhere. It doesn't seem to be anywhere inside or outside of the ship. If I get in the car, I get killed by the stalker. If I leave before unscrewing the grate, I also get killed by the stalker.

If anyone has finished the game yet, a small hint (like just the location of the phone or basically the next minor task) would be appreciated.

EDIT: I found the method to get to the credits. Very strange that one would be allowed to go so far as to get the car key only for an inevitable bad ending. I hope I'm just missing something and there is in fact a different ending hiding somewhere just out of reach.

I finished and my tip is to take a better look because there is an interaction to do with the brick

Is there a way to escape the coffee shop at the end besides dropping the brick? Going in the car always gets me killed.

i found only 2 endings. one is dropping the brick on his head. the other is escaping thru the vent with the screw driver (the bathroom) and driving off. however both endings get you killed

You can use the brick from the roof.
