I just beat Twin Eagle tonight. A couple of nights ago I scrolled all the way up to the castle level but got scrapped at the beginning so all of my powerups and bombs were gone. Given that there are very few power-up and bomb opportunities on this level and it is full of missile launchers. So when I managed to crawl to the castle, dying repeatedly along the way and using up my continues, I sat there for 30 seconds firing my useless default weapons and lost the rest of my lives before I even put a dent in the castle. For years, I never thought I'd get that close and then tonight I beat it. I still had 13 bombs left in my inventory. Two speed boosts and a level 4 missile power-up and I spent at most 15 seconds razing the castle to the ground. I was so excited. I had never seen the ending to the game before. Now I have no reason to ever play it again. lol
