I'm not good at this kind of games(played for half an hour and only made it to round 3LOL) but I really enjoy it. Every round I try some new combination and purchase for different items, that's quite fascinating. I think it will be high in potential, if you're willing to develop it more in the future.
Also it amazed me how good the game perform, intact UI, sound, smooth playing experience and feedback. That's a very high level of completion from my point of view. Anyway, this is an awesome game. :)
