I'd imagine a lot of people here have heard of this game by now, but in case anyone hasn't, it's a fantastic 2D platformer for the PC. Free, and created entirely by just one Japanese man in his spare time. Given that, it's amazing how polished, deep and perfect it feels - far more so than many similar looking commercial games. It's honestly one of the best games I played last year. Download the PC version here, and the English translation patch here. There's a mac version available as well, game here and patch here.
