This a great looking game with fun gameplay. I also enjoyed the music and SFX. I don't really have much to say, because this is honestly just a great game.
The only issue I had was that you could start off buying something other than a money maker and immediately have no way of winning anymore.
I also would have liked some more obvious feedback when something get destroyed. A few times I was focusing on something else and only later realised that something important had gotten blown up. E.g. a small but noticeable destruction animation to draw the eye might have been helpful.
But overall, this is simply excellent. I enjoyed playing it!
