Mega Man 11 isn't perfect. It isn't a severely flawed game, but some of its flaws can really stand out. For the most part the level design is really good. There are many moments that encourage players to use the double gear system and the levels are lengthy enough that they can keep you busy. The difficulty of some levels, however, is definitely going to get to some players. For the most part any screw ups are your own, but there's a lot of trial and error in learning some of the levels, and even worse is that Mega Man 11 has a limited life count. If you get a game over it's back to the beginning of a level for you. The levels put up a great challenge, but their length and (in some levels) hazards can make starting the entire thing over again feel like a test in frustration. Even Mega Man veterans will have to slow down and really take time to learn these levels.
LIkewise, while many of the levels are incredibly well designed such as Block Man's stage (which makes a great tutorial for the double gear system) or Tundra Man's stage, this just makes it more obvious when level design falls short of expectations. Bounce Man's stage may be the single most frustrating stage to appear in a classic Mega Man game, and the flame wall in Torch Man's stage is more frustrating than challenging.
The series centers on Link, the playable character and chief protagonist. Link is often given the task of rescuing Princess Zelda and the kingdom of Hyrule from Ganon, who is the principal antagonist of the series; however, other settings and antagonists have appeared in several games. The plots commonly involve a relic known as the Triforce, a set of three omnipotent golden triangles. The protagonist in each game is usually not the same incarnation of Link, but a few exceptions exist.
Though Capcom owns the rights to all Mega Man games and has been responsible for the development of all of his console titles, it has in the past licensed the Mega Man character to other companies for PC releases. Mega Man and Mega Man III (with no relation to the NES games of the same name) were developed by the US-based Hi-Tech Expressions, the Mega Man game published on the Game Gear by Sega, and Rockman Strategy was developed and released exclusively in China by AcerTWP. Neither title has since been regarded by Capcom as an official Mega Man series game.
