So far I've played into Hotline Miami, Little Inferno and Thomas was Alone. All three are pretty good, but the latter two stood out to me especially and are worth the bundle already.
Little Inferno is a "game" about putting all kinds of things into a fireplace, burning them, and thus getting money to order more things to burn. It might not sound like much, but it's actually quite the experience.
Thomas was Alone is a neat platformer with an excellent narration that gives character to *rectangles*. It's probably the only game that you will find where you will refer to rectangles by name and care for them due to their personality. (The whole narration is done wonderfully by Danny Wallace, whom some of you may know as the voice of Shaun Hastings in the Assassin's Creed series)
So if you were pondering about this Bundle, maybe this can help you shape your opinion
