This game has a neat concept, but I found it difficult to control because the camera would bounce around quite a bit sometimes and cause momentary disorientation. Some audio / sound effects would really enhance the game. Really nice 3d graphics.
Maybe the 1st few levels could be slower-paced with fewer orbs to help the player get accustomed to the gameplay. And a tutorial or demo that gently introduces the rules of the game would be a welcome addition.
Including the level editor is a really nice extra feature! Possibly a higher 3/4 3d view instead of a 1st person 3d view would improve the overall playability of the game, but that 3/4 perspective might not be what you were aiming for in your design of the game. It's neat how the gamejam's "edges" theme was incorporated into this game, and it's also nice that you can't fall off the edges which would make the gameplay very difficult!
