I have an Idea for the Boomerang/Ultra Rang:
-The Boomerang/Ultra Rang will now fly in a straight line forwards and will also return without any curves. (so it will attack two times)
-Also make it so you can charge it up. The more its charged, the bigger it will be, and it will have more cooldown.
-At max charge it will ignore weak points and will have a VERY long cooldown. (Like 30 seconds).
