Well, this little game is very unbalanced and... primitive. White weapons are almost not playable (why the heck is there plenty of them, when they function almost the same?), most bosses are *very* easy (it's only the matter of big firepower, e.g. Multi Cannons and sometimes speed). Upgrades are unbalanced (not enough time and experience to max anything; I felt that no matter what I choose, for the gameplay it will be the same. So 2/5
