Oh this is just beautiful! The little robot is super-cute (reminds me of Wall-e) and the gameplay is simple while being a real challenge. Presentation is slick as can be, too. The only thing I didn't appreciate at first was that you get more cards - I thought I had to collect all the power with just my opening cards, which I knew was impossible :) But once I realised that you get more cards (and rules) and just have to ensure the battery doesn't drain down, then I was consumed by this for far too long. Great stuff!
