The visuals are awesome! I get the tie in to the theme but I think it may have come through a little clearer if the energy was generated by the hamsters on a wheel, but still, I liked it! One thing: I did lose a hamster by accidentally dropping it outside of the rooms - I had a baby hammy so it was okay and I didn't lock myself out of progressing, but I do think that could be something to watch for if it happened when the player only has the initial two hamsters =D
