Beat Stage 4

Luckily my playthrough went really fast, and I am saying "luckily" because I found a continue code by pressing the classic "all buttons" on game over screen and surely more of that music and I would have gone insane. The chopper controls are good the only problem is that speed is slow and makes hard to dodge bullets and hit enemies. Probably bosses at the end of the stages and more levels would have been a good addition to the game.
