> Go into desert
You venture into the desert. After a few hours of walking, you start to get thirsty.
> drink water
You don't have any with you!
> look for water
You look around for a water source in the middle of the desert. A few second laters, you realise how futile this is, and start to walk back the way you came. Unfortunately, you can't find the forest you left anywhere, and the desert seems to go on for an eternity. Seeing as you didn't pick up the ring of infinite supplies earlier, you die of thirst and/or hunger! Game over!
Suddenly, you wake up!
You sigh with relief. "Phew, it was all just a dream!"
You're back in the nondescript room. Now to start your adventure for real.
