A small update which adds a few things and changes a few more.

• Added most of the Upgrade logic that allows a player to upgrade their Gravity powers.

• Added two new levels; exploring some new game mechanics and puzzles in them.

• Changed and tightened up the physics and mechanics of the Gravity powers.

• Added the ability to pull objects towards the player instead of just pushing them; in addition a player can now push/pull an object closer/farther away while it is being Gravity Grabbed.

• Tweaked how much/fast energy a player uses at the start of the game so the pace of each level is not slowed down by having to wait for energy to regen as often.

Unfortunately, there is still no death/fail logic. I am still torn between having a player have to restart the whole stage if their energy drops below 0 or just have them respawn.

Also still desperately need to add more sounds to the game and finish up the various graphics for the GUIs.
