I don't have the money to try the game, but it looks really good! One thing I would say in response to the post is that (for me) stories make a puzzle game far more playable. However addictive a puzzle game, I get this annoying feeling I am wasting my time playing them - complete one level, move on to the next level, the progression feels a lot more arbitary when compared to uncovering a story.
Yet take a game like portal, and imagine it without the story - It wouldn't have been as interesting. They took an interesting concept for a level-based puzzle game, and wrote a story to give it a context, and add an extra dimension to it. Without the story I don't think I would have enjoyed it nearly as much. Or thomas was alone - the gameplay tiself was fun, if a relatively basic 2D platformer. Add the story and you have something special
Soooooo... I imagine you made the right choice
