i totally agree with AstralBlades, also the fact that after a few levels powerups become useless and theres no save feature completely let this game down
don't know why people complain about the difficulty of this game, the badge is meant to be hard to get
its a good game and seeing as you have infinite lives not too hard if somewhat labourious
this game is shockingly bad, from its lack of save system, limited weapon upgrades to its extremely repetitive gameplay.
and my suggestion for the last level is just keep running if you fire, it induces lag making the game stretch on for eternity
