You go around shooting enemies. That’s basically it. You have weapons and upgrades that go up to level 4 starting with a weak blue laser beamy thing called ptershot. It’s rapid fire but it isn’t spread. I don’t suggest getting this. It’s upgrade/weapon look is a blue circle with 3 lines that flash. It stays as the same shot.
Next, is pterboom. Shoots a boomerang out. It’s purple. it goes at an angle. At level 2 you shoot 2 boomerangs and at level 3 you shoot 2 boomerangs. At level 4 you shoot 2 GIANT boomerangs. This is my second most favorite weapon. Upgrade is a purple circle with a purple line spinning inside.
