My favorite XBLA game is Braid, hands down. The game starts right off by displaying its impressive and unique art style. The story is told between chapters as scenes that had happened in life. Now, while the story and unique style of Braid are great, that's actually the worth of it. The game at first seems to play like your ordinary platformer via symbolism, as if you were mario who jumped onto the gooba. You slowly then realize it's not all about getting from point A to point B, you have to figure out how to get there.
This is where the game gets interesting with its first introduction of puzzles. Seems fair enough, get the key an open the door and you can continue. Oh look, you can just walk right through the entire stage and before you know it, you're at the castle and get the notalgic line "Sorry, but the princess is in another castle. So you're free to go to the second part, you find some more literature as if it were written in a third person perspective. You continue on into Chapter 2 as you would in Chapter 1, but there's a slight difference.
What's this? I have to sold a moderately difficult puzzle? yes, it's platforming puzzle game. Never judge a game by its cover, you may be pleasantly surprised. He then became aware that he could use time travel. So he let the enemy grab the key from him, he jumped down, grabbed the key and rewinded back in time to have the key to open the door on the other side of the ditch. At this point by observing the key and door you can see that neither is affected when he travels back in time, they are immune, Just knowing this brings in an entirely different element to the game. So you go through the game, fight one boss using you time travel ability, not a very hard fight.
After a few worlds, you finally to the end and are astounded to see the same dinosaur approach you and say "Was the pricess ever real?" It left me astounded, but I noticed the was a ladder to the toped that was locked in several places. I decided to go back into the other worlds only to discover each stage has several puzzle pieces within them and a dfiferent way to get each. This is where some gamers have to stress their minds to figure out the puzzle. It's one of those satisfying moments you get in a game when you make a big accomplishment. Once you're gathered all the puzzle pieces you have to place them in place on the frame within the world.
This will unlock one of the locks on the tall ladder back at the main room. You basically have to beat each level before you can get up . I myself am still working on getting all the puzzles complete and I have to admit, it's one of the best damned games I have ever played. It's entertaining, enjoyable, artistic, great controls, very intuitive, etc. It's just something that anyone who owns a 360 needs to buy. It's only $15 too, so cmon.
