I've known about this indie game for a while, but I only decided to try it out a few days ago.
And I have to say that Treasure Adventure Game is simply amazing ^^
Has anyone beside me heard about it? If not, here's some fancy trailer: http://www.youtube.com/watch?v=b-YvT2y3_I0
It is a retro looking 2D non-linear exploration game, its genre is known as 'metroidvania'.
The world is huge and the great thing is that the game does not tell you exactly what to do and where to go, making exploring way more enjoyable than in most modern games.
It's available for free, download here: http://www.gamefront.com/files/21082099 ... _1.0.1.zip
