Super Contra NES 1990 - Area 2

I have never made it this far previously. I have absolutely no idea how hard this can be, but here it is. For the original game, all the odds are 2D side view adventure, and even level will be a 3D going forward kind of adventure. However, on this Super C, I think this is for the first time I'm playing with top view. I remember I saw this demo back in the 90's but little do I remember I have tried it by myself. Once agian, I didn't get my own unit of Nintendo until 1996, when everybody was talking about Playstation, I was happily fiddling with my Super Mario Bros with my dad's 26' TV.
