did anyone notice that this is almost an exact rip off of U.N. Squadron for the snes? all three of the first levels are so far exactly the same even down to when, where and how the enemy arrive and fight. and what about the hidden health refills being in the same spots and the same list of special guns. about the only thing i didn't see them copy is the 3 pilots to choose from and the random supply trucks encounters.
Are you sure that "use %" isn't checked? and that you are using the textbox on the right? (the one of the left is for per second amounts)
