Pretty nice, simple improvements, I would have loved: showing how much rent is due while playing and counting your money up during the animation of "payout".
Some more mechanics like a "reroll" on the slection would have helped for a bit more control, but I knew what you were going for and the effects of the different stocks were versatile.
haha and I just broke it by pressing SPIN like 100 times, I think you need to disable the button.
