I'm surprised there isn't a buy X floors in the game.

I'm surprised that Nimblebit has added a buy X floors (as long as you have the coins) as a tech tree upgrades or legendary lounge upgrade.

Something like:

Level 1: Buy up to 2 floors.

Level 2: Buy up to 3 floors.

Level 3: Buy up to 5 floors.

Level 4: Buy up to 7 floors.

Level 5: Buy up to 10 floors.
