In Portal, I am continually told that I will
be receiving cake for all my hard work
but in the final room I keep dying.
How do I avoid dying so that I can
get the cake?
Answer
You need to think with Portals!
Look up in the direction you are heading to the fire; you can spawn a portal on the wall up there, one to your right, and teleport out of danger.
After that, keep trying to reach the party to get your promised cake!
