In the fun skill game Noob Nightmare Arcade, you have to stay on a column on top of a mountain for as long as you can.
It might seem hard to stay balanced on a huge column on top of the tallest mountain. Now make fireballs fall from the sky, make the column invisible, and watch out for a big knight who comes after you. Some might say it's a real nightmare. To beat each level, you must stay alive for 15 seconds.
Have fun and good luck!
