Why do sequels always fall short?!

I absolutely loved the first one, and its not to say that this one is bad, but it lost the appeal of the first. The 8 bit Nintendo look killed it! What is the look of this one? Not anything retro, which is what they captured perfectly with the original! Aargh!!! Its just not as fun! Its much harder, but not in a challenging way; Its just harder. Mega man 5 is visually unchanged from the first, and the first league of evil reminded me of that amazing fun! Why did they stray so far! I hate writing this, but its already my least played iOS game. I love you guys, but please release more levels for the original! Still, its worth the $2.99- I guess Im already a nostalgic LOE fan!
