[Not compatable with mobile devices] The first prototype of a bigger project. Press the A and D buttons to move the sphere left and right respectively. Press the SPACE bar to reverse the sphere's gravity (there is no way to jump). [NOTE: THIS IS ONLY A PROTOTYPE AND WILL NOT RECEIVE ANY FURTHER UPDATES; INSTEAD, THE NEXT PROTOTYPE WILL BE BIGGER AND MORE PROGRESSIVE]
