Recommendations for freeware/free indie games?

I was just wondering if anyone has any good recommendations for freeware or free indie games. I enjoy playing just about any genre, so any good games will do.

ib is a great freeware horror game: http://www.mediafire.com/?cjsrb04pxtg71ai

Katawa Shoujo.

I Wanna Be The Guy: Gaiden (LINK) - A "Hardcore" Contra-like game where everything wants to kill you.

Psycho Waluigi (LINK) An extremely well-made Super Mario "clone." Honestly, this is so good that I swear Nintendo had something to do with it. Oh, it focuses on Waluigi and his "Psychic powers." The game is fucking awesome.

Seedling (LINK) A Zelda-like game that has a really good story, slew of characters, and tough enemies/bosses. I really recommend giving this one a shot if you happened to enjoy Zelda-esque Dungeon-Crawlers.

Ib (LINK) A 2-D "SNES style" Horror game that actually gets to you at certain points. Overall it is incredibly enjoyable and some of the puzzles will leave you scratching your head while a woman in a painting chases you - intense.

Treasure Adventure Game (LINK) A 2-D Platformer RPG. Don't let the simple name turn you away, this one is really "deep" and a lot of fun. I recommend giving this a shot if you like exploration and RPG's.

That's all I've got for now, there are a ton out there. I hope you enjoy them as much as I have. Also, check out this guy. He is generally where I get a lot of the "spotlight" indie games and occasionally they are free. :)

Realm of the Mad God, it's free on Steam, it's free on the browsers.

• Beneath a Steel Sky
• Tyrian
• Spelunky (original)
• Cave Story (original)
• Chex Quest 3
• Marathon series
• Chzo Mythos series
• Super Crate Box
• Jetpack
• God of Thunder
• Stealth Bastard
• DoomRL

I've always enjoyed Iji. Cool weapons, interesting story, and you'll probably want to play it more than once.

@Video_Game_King: The concept sounds unique, but I'm unsure whether I would like to delve into this.

Kingdom Rush is pretty great if you like tower defense.

@ManotheBard: Don't be scared! Just embrace it!

Yume Nikki is a great surrealist exploration game with a wiki full of people writing long interpretations of the game's meaning if you're into that sort of thing.
