level 14 is impossible
cant do it to save my life i dont know how many time ive tried excellent is easy enough to get but brilliant is ridiculous even with full meteor costing 100 a pop
its a good game i like it i gave it 4/5 but there are many things to improve.
you shouldnt be able to use a weapon over and over but for the better weapons have to wait before you can fire it again gets quicker down the tiers.
also have the option for a shield or something that can stop the weapon taking off max damage
