Very zen. Would be nice to have your own space you can come back to and choose the background, drag in all the creatures you've captured, and basically customize it to be "yours". And then go back to combining and discovering and capturing in these other spaces you're whisked off to. Some simple animations on the creatures (and letting them walk around on screen or something) would also make them feel way more alive, but that's admittedly a lot more work!
Good music choice, too. :)
