I think something great to add to the game would be more customization. One thing I think would be great to customize is obstacle spawn (bumpers, black holes, portals). Also, I think it would be cool to have some customization with the weapons, such as making it so you can only get certain weapons, (to a point obviously, A lvl 1 player cannot just use nukes and black holes). Feel free to leave any customization suggestions you may have.
