A torch would be useful in the dark… Make one! (Pages 22-23 in the book)
SPOILER
What you need:
Bike lamp
Pincer, copper and iron nails (on the workbench)
Copper wire (in the first cellar, on the shelf)
How to use:
Find the crate of apples in cellar 1. It is below the shelf on the left (access it from the close-up on the left shelf - down arrow). Use the iron and copper nails on the apples. Combine the wire and the pincer in the Inventory to cut short and long pieces. Attach first the short, then the long wires to the nails. Fix the lamp on the crate – and the „apple battery” is ready! Place it on the baby stroller in cellar 2 for easy carrying. Balázs can now enter the next location which is a corridor leading to a locked iron grate.
If a switch is out of reach, you need a „remote controller”.
Air is good for so many different things! A wave of pressure, for example. (Page 16 of the book)
A strong magnet is not only for collecting pins.
SPOILER
What you need:
PVC pipe (on the floor)
How to use:
Combine the PVC pipe with the corn kernels in the Inventory to make a „blowpipe”. Look through the iron grate and use the blowpipe on the light switch.
Combine the bow with the magnet and pick up the key behind the door. Use it on the lock. The next location is a basement room with two doors on the other side. One is locked by a chain; the other is protected by a combination lock.
