Liking the art style

Im enjoying the art style but I wont lie some days it bothers me a bit but thats my problem, the game is great though Im not really liking the hole get upgrades in order or some upgrades you need to use real money because I dont know what it is but it doesnt really feel like a full game or a game I want to spend money I think its the lack of guns or something but other then that this games good Ive been enjoying it I come in shot a few gangsters then stop
