I love the idea and it´s really intuitive to play. And I must say that I love the visual style: very clean and beautiful! However, the rewards are too rng dependant, you need to get a combo to generate coins in the first or second round or you are dead, now it's a fun puzzle to think if you can make it to the end of the round but very frustrating. I think it's a great game and I encorage you to expand on the idea. Great job!
