Honestly this game was fun and great in the beginning. I even purchased the full version, but on the business class level 9 is impossible to beat without buying the air freshener for 0.99 cents. I like the game a lot, so I bought it anyways, but I thought you get more of the air freshener permanently. NOPE! You buy it, you get five and once you used it all, you have to buy more. It's only a one time use and the air fresheners don't even fill the hearts fully. I didn't get to pass level 9 and the only way I could beat it is to pay more. Honestly this was such a waste of money. You pay 2.99 for another 9 levels and you HAVE to pay 0.99 cents more to beat level 9, but if you're like me where you still couldn't beat it with the air fresheners, than you'd have to spend more on this game. I wouldn't spend anymore on a game that I know I'd get bored of and delete it in the future anyways. This is such a scam.
