Economical 8.5 out of 10, too much capitalism.
But seriously though, this is a really fun game! But thing is, the goal presented (Reach the goal with the most coins possible) wasn't very fun.
The goal that I found was "How do I cheese this level?"
And that is certainly not the intended goal. But I found the new goal to be way more fun than the presented goal.
So now I have a game idea and bankruptcy but it was all worth it.
Actual score? 8 out of 10. The intended goal wasn't engaging enough fr me to strive for it.
Possible solution? Make it where you can't go in the red. As soon as you can't buy any more blocks/hammers, you shouldn't be able to buy any more blocks/hammers. That way, I would have to think about my uses of the tools presented to me and I would be more likely to try to get the intended goal.
