Fun and cute game. My only complaint is the tiny shmush are a bit too tiny for me. I was having a hard time getting it to register I was clicking on them. Other than that I like the game. :)
You definitely got the theme of less is more as far as I'm concerned. If you flick too hard you can die off screen so its more useful to hold back AND if you get less health you split and the game becomes more challenging to micromanage the shmushes. You get a 5 on theme from me.
