The controls need some work.
I actually really like the ideas that this game puts out; there's nothing else quite entirely like it. The leveling system is well thought out (by the time you need to sweep the entire stage for junk parts to level up, you can GENERALLY just start flinging enemies), and your mode of attack is quite unique.
But DAMN is it hard to control your plane. It's easy early on when you can basically just hover above an enemy and drop stuff to kill them at your leisure, but once you start getting to enemies that will shoot your ass out of the sky, mouse control feels VERY imprecise and dodgy. It does not help at all that in your frantic attempts to sweep the field of vaulable EXP/ammo/goodies, your mouse pointer- which you cannot see or even BEGIN to determine the location of- will FREQUENTLY go flying out of the Flash window, confusing a player greatly and making it hard to sweep around like you need to in order to live beyond the first three or so missions. I also think it's a VERY questionable decision to force a player to 'cash in' all the scrap that they didn't pick up for Ultimately Useless Points. At least give us a few seconds to make a mad dash for what's left, or better, don't remove it from the playing field at all. The game seems to be able to handle all the sprites.
Honestly, this is a really good game, and it has to potential to be incredible. But whip up a keyboard control scheme or something, at LEAST as an alternate mode of control. With that, I think this game could be one of the greats.
