Guacamelee is an action platform (very much in the spirit of Metroid and Castlevania) indie game that was recently released on Steam (before it was just PS3/Vita exclusive). Now, I was REALLY surprised at how good this game is. The combat is incredibly fun, it is a very polished game, and the art style is really appealing. It has some really solid gameplay, and is just fun to play. I'm legitimately surprised that I don't see more people talking about this, since this is one of the best indie games I've played, period. If you have the spare cash, I'd highly recommend it. Here are some videos if you want to get a better idea of what this game is like:
