Double Bros is a very interesting online game in which there are many levels and a shop from where you can buy a lot of things in the course of the game play. It is a challenging game because you are going to have to use two different sets of controls to control the two characters simultaneously. They should be made to jump and dodge with very good timing to avoid all the obstacles that come in their way to go to the end of each level. They will come across gems worth collecting. Yes the difficulty of the game play will continue to rise with each passing level but the upgrades available in the shop will be helpful to negotiate those difficulties.
