Orbitor is a beautiful 2D exploration game made with Unity. You play as a small space ship who flies around in space, jumping in between large bubbles which act as gravity fields, pulling you back towards them. You can accelerate with the spacebar and turn yourself to the left or right using the arrow keys. Inside of the larger gravity bubbles there are smaller circles which you will begin to orbit rapidly when coming near to them. You can then press space to slingshot away from them and pick up speed. This game is highly physics-based, and even allows you to slow down time by pressing z! In this game, you can shoot from bubble to bubble as much as you want, but recently the game became level-based with a large warp device (4th picture below) attached to the final bubble through which you can warp to the next level. The game is a 2D Unity game with awe-inspiring graphics, a beautiful soundtrack, and hours of replayability, this game shows serious potential, and in its development phase is already one of the best 2D games I've ever seen! You can download the free demo here or play an earlier version in-browser (with Unity Web Player) on the same page.
