Favorite Freeware games?

Much obliged, it's always nice to see this thread floating along. A lot of GREAT games in here. And, unsure if it's been mentioned, but can I throw in Katawa Shoujo?

Station 37 is good while it lasts, but the ending... What ending? Seriously, the game ends at what feels more like the final part of a prologue.

It's among a ton of games I'll have to write about in the freeware recommendations thread. I loved the wonderful pixel art but it'evident that, for one reason or another, the authors got bored. I have no other way to explain how you reach the last trapped person in the hotel and then there's an alien invasion that destroys most of humanity, you kill the boss and... That's all. And before you started that only level, it also teases you with future upgrades for the axe and fire extinguisher. Great potential killed by lack of interest of its creators.

Anybody know some good stuff I can actually play on a Mac?

Do Flash games count? Because The Bright In The Screen needs more love.
