Catchy but aaaargh so hard! It's addicting a while, but when you start hesitating in front of certain traps, or just getting hit by bad combinations over and over... gets a bit aggravating.
I assume it's one of those games that gets better and better the more you play though. Easier with practice. And there's really nothing wrong with the mechanics, just that spaces all feel somewhat small and traps easy to get stuck in, an uninviting contrast to that endless stream of money. Think it'll take some time to get to that 50K...
Love the design though, and the music. Great atmosphere as always.
