Gravity Aliens

Alien Gravity - Teach the naughty aliens the art of gravity. Get to the door using nothing but physics as you chop and change the gravity of the moment, floating up and down and essentially walking on walls to avoid the holes and the fire boxes!

This game will help develop your basic knowledge of gravity and science. Remember, gravity pulls everything to the centre, so on earth (normal mode) it pulls us down towards the centre of the earth, hence why we cant just float off. Flip the gravity in this game and you will be pulled upwards allowing you to walk on the walls up above. This game requires a delicate understanding of when to flip the gravity to best achieve the outcome of reaching the exit door! Enjoy!
