The best way to get started is to just play the game. You’ll be taken through the tutorial room first which gives you all the basics.
However, some of the key commands you’ll need to use are:
- look around
- look behind the table (or under, on, in front of…)
- pick up the key
- unlock the door
- go through the door
- what am I carrying?
As you explore the room, don’t be afraid to try all sorts of actions to try and escape. Maybe you need to unlock a door, empty a bucket, smash a glass jar or turn on a lamp. The possibilities are endless, so explore!
