What little tips can you share, that don't give away game elements themselves (so "go to X for Y plant" doesn't count)? What advice do you have to someone new to the game? Please don't post spoilers, even mild ones.

I'll start.

- If you're out of control, running down a hill, try slowing yourself down by turning to one side or the other until you're running up another slope. On a long slope, you can even turn 180 degrees back up the slope you're on. Or, just hold down the S key to slow you quickly to a stop.

- Remember that the Bunsen burners[en.wikipedia.org] you sometimes see in laboratories act as lights and save the game.

- Don't forget that you sometimes need to crouch to pick things up
