There should be a way to organize the inventory based on items, and for the "sell all" to apply to those categories.
If you are having trouble against the ninjas, their ability is guillotine blade, and it does damage based on your defense. If you take of all of your armor, then you have 0 defense and it does 0 damage, so you cant be 1 shotted.
The item drop system is really annoying; The fact that you get a million noob items after each battle is just stupid. This is exacerbated by the drag-drop system.
*Takes flag, has 1 health left. Shoots enemy in the head until they reload their explosive, and teleports out right when he shoots it, causing enemy soldier to commit suicide* U mad brah?
