If you like old-school 2D action platform games, you might be interested in The Legend of Princess. It's by Joakim Sandberg, the genius behind Noitu Love 1 & 2, and is free to download.
There's no getting away from the fact that the protagonist bears an uncanny resemblance to Zelda hero, Link, and the graphical style is wonderful, while the music is retro cool.
There's only one level, but there's plenty of replay value, with some cracking bosses to take down.
As it's free, you'd be mad to miss it.
