I supose you didn't came to see the secrets and you rushed like getting Curly's Machine Gun and not wait till the Spur or getting the Nemesis. Bet you didn't know the secret zones and tsave Curly and beat he Hell level to understand the secret story. It's not only a good well done game, it's a game that has A LOT of little details you don't know but when you realise it, it surprises you. Words from the unique Daisuke Amaya:
-Levels are designed so you always know the paths.
-Graphics are made simple and recognizable.
-Quote's design is made to be visible in dark places (white skin) and lighted places (dark clothes)
-Everything makes a little sound: Quote's steps, the experience shards... That makes the game more alive.
-Simple control to make it easier to people, but not a simple game experience.
-History has some deep moments, not by heavy dialogs, but with situations like the labyrith and the Curlyy's drowning trying to save your life. More implicit that explicit story.
-The music... Welll, verybodo knows the main song... and how the Mimiga Village has a happy and the a sad song, that makes you feel that something happened.
-Maybe you didint notice it, but enemies react too you: ou attack, they attack. Balrog knows when you jump... etc... That's something really hard to make.
Now, dare you to say that the game is not awesome.
