Upgrades are vastly more expensive compared to the funds you earn. 4450/30 seconds is terrible when most everything is between 200,000 to 2,000,000. In order to be comparable to money earned, the prices of everything should be 1/4 of what it is now. It would still require some saving up for some things, but I could still make some decent progress while actively playing. It's really not all that interactive when you're just waiting for enough funds. I get bored and with nothing to draw me back.

Neat game, but you almost can not progress without watching ads (and they show up every 15 seconds). You absolutely will not be able to meet business contract requirements without diamonds, which are impossible to get a sufficient amount of, without spending real money. I like it so far, but I'm not sure how long I'll be playing it if it's not reasonable. Idle is one thing, impossible without spending real money, is another.

The wheel is quite obviously rigged. I spin it daily, and I always get one of two things. The ads are at least a minute a pop, and at some point, it becomes impossible to advance without spending money. You need gems and a lot of them to upgrade paintings in each office, but gems are almost impossible to get. Ads are too long, pay to play, and rigged to get you to spend money.
