Gravit Eye will start you off with a simple tutorial and move you on to a few more levels to help you fiddle with the controls and figure out the game. You'll use the arrows or the W,A,S and D keys on your keyboard which will have you use either X or J to jump. Your goal in every level is to meet up with the red bullseye so you can be transported to the next level. There are objects you'll get to interact with like springs and arrows that will change the gravity of the area. Try this super fun and addictive game now and you'll be happy you did. Good luck!
