If you've played Roblox tycoons before, you should understand this. If you have enough money to buy something, it will increase the money you get per 1/2 second. It will play a sound if you don't have enough money to buy something. Press the right arrow to go to the buildings background.
The first dropper is free. Hint: You can tell how much a dropper (and building!) is worth by looking at the numbers on it. If this is boring, play the other updates. (Including v0.2(Coming soon)!)
