I like it, I think it has potential. The game could use some optimizing though. Pro Tip: In Unity set objects that don't move and don't have any dynamic scripts to Static with the static toggle in the inspector panel. Then go to the Occlusion Culling Panel ((Top Menu) Window -> Rendering -> Occlusion Culling). In this Occlusion Culling Window click the bake button. Once it finishes baking, you should see a sort wire frame-like group of cubes (if you're in the " Visualization" section). These represent the areas that will be culled when the Main Camera isn't looking in the direction of them. Basically when playing the game now, the only objects draw are going to be the ones that are in the view of the camera. You can see this in action if you click play in the Unity Editor, put the scene view side-by-side with the game view and you should notice parts of the level will hide when you look away from them while in the game view.
I think this game has potential, keep working on it and it may get some attention. Just polish it up a bit. Add a Main Menu and Pause Menu with some options/settings menus for people with low-end machines and you got yourself a decent game. I like the color-like splatoon/portal mechanic, very neat.
