The game is called "Blow them back to the surface" but I had to shorten the newgrounds title

The earth has become over populated. With no where to live the humans started to move underground. They found themselves is a place where they are not wanted.

You play as a moleman in a small ship shaped like a ball that has a big gun. Your ship bounces like a ball and the object of the game is to change the direction of gravity to maneuver and shoot bombs at your enemies and there homes. You can hover if you switch the gravity back and forth.

The controls are

w or up arrow reverses the gravity so you fall up
s down arrow is normal gravity so you fall down
a or left arrow nudges you left
d or right arrow nudges you right
x is for the shield and when you turn off the shield it recharges.
q or the "Q" button changes the quality of the game
"Shake" button stops the level from shaking.

Please go though the tutorial that is on the menu screen

This game can be cpu intensive so if you have an old computer you might have problems.
