I'm on the first map and can't get out! I hope the whole game isn't like this. I'm pressing a red button to open a door, but as soon as I leave the button, the door closes and I can't get there soon enough to get through. Anyone have some help for me? Thanks!

Hey mate. You should try to find something heavy to push the button, instead of yourself. Possibly a rock.

You know you can pick up objects, right ?

As stated above. If you hold down the Left mouse button or the ctrl key, you will activate the character's "tractor beam" which can pick up small objects.

The game itself is overall pretty easy. I went through it in a few hours. I had to look up a walkthrough for 1 puzzle. Otherwise no issues.
