noticed only two of you did the challenge so I eliminated based on past activity.
This round is called "Instant Elimination"

There will be a challenge done and whoever wins it will have the power to instantly eliminate one of the other three!   If you're a target in this game, you defiantly want to win this one!

Your game is an old game I loved growing up as a little kid! One of the first game I would ever play!
It's called Bubble Bobble here are the controls

When you get to the start screen hit the CTRL button .    CTRL shoots bubbles the arrow keys move you left and right, space jumps. Shoot the bad guys with bubbles then go pop the bubbles at the top of the screen.
