(BTW: CAVESTORY IS COMING OUT TO WIIWARE)
* Cave Story / Doukutsu Monogatari *
http://en.wikipedia.org/wiki/Cave_Story
Classic-styled platformer action. Afaik, completely made by one Japanese dude. Your guns level up. The art is pretty unique. Controls are good, interesting characters, fun to play. If you haven't heard of it, you're not a PC gamer.

Action platformer, with a style reminiscent of Out Of This World, I haven't had the time to play it yet, but it looks fucking wicked.
Even though I didn't play Out Of This World much! I hated that game, it scared the crap outta me when I was 8. XD But I love the style.
* La Mulana and Maze of Galious *

Maze of Galious: http://www.braingames.getput.com/mog/
MoG is a remake of a really old MSX game (MSX is a PC only released in Japan and Europe, but had lots of interesting games. Metal Gear started out on the MSX...)
Maze of Galious is a graphical / audio update, while La Mulana is sort of an "MSX fan game", made in the style of some old MSX platformers. La Mulana is really hard, but these are pretty neat to check out.
Or watch the Lets Play of...: http://www.youtube.com/view_play_list?p ... 18FBD81577
(For the record, I'm in love with Deceased Crab, although I've never met him or spoken to him)
* Aquaria *
http://www.bit-blot.com/aquaria/
An interesting sort of underwater exploration game, this game is really beautiful and fun to play, too. ( I've only played the demo, I don't know much about it ^^; )
* Braid *
http://braid-game.com/
Braid is a puzzle game that plays as a platformer for the XBLA. Your character has time travel abilities, and in each world you get a new sort of skill to play around with. The puzzles can be very difficult, but the game is super awesome and the meaning behind it is kind of creepy.
