They should add a system that when you reach 10-10 (when you finish the main story) you could unlock 2x speed for stages because once you reach that point in the game it becomes super grindie for example farming for catalyst or leveling up fooders, this will benefit both sides, The faster you clear stages the more energy you are burning more energy burning, more refills you spend. This should be a opcion that you could activate and disactive. Hope you guys enjoy this idea
