Pro: Awesome new concepts over the original Crush the Castle.
Pro: Integrated user design functionality with instant returns on Kong.
Con: Not enough levels to experiment with the new concepts without having to pay. Gratuities should not be considered compulsory for content - I have this problem with Berzerk Games as well.
Con: Doesn't run well on my system. Yes, I'm on a toaster, but I've run games with similar instances of physics with not as much issue as this.
All in all, it's a 4/5 for me. I had fun with it.
