While there are tons of options to handle the endless war, it can also be surprisingly restrictive. Only one main and one secondary weapon can be equipped at a time, and they can not be turned on until a level is over. Power-ups are also strangely non-existent during the game, the players, they must first be acquired in the workshop. In a weird way I'm put off a bit on the speed of enemy missiles, which are much slower. I have no idea why this is so or why it bugs me, but it works.
