Not a bad sim-business type game. Could be a lot better with some polish.
My suggestions for improvements:
1. I'm seeing a lot of mouse lag. It's frustrating to play with, and almost impossible to click on anything moving, like customers.
2. The interface is a little clunky. I mean it's all functional, just not very smooth to use. For example, if I click to build something, then want to build something else, if I don't click exactly right on the icon, it will build that first thing under the icon I was trying to click for the second thing. I do like how I can drag to build multiple walls and floors, but it breaks sometimes and I have to start over. Also when I build doors the flooring under them disappears.
3. The first few customers that came in, some were happy and some would get upset. The upset ones would tell me why they were upset - no food, not enough seating, etc. But after a while, customers are all showing as happy but still my satisfaction percentage keeps dropping. You should make it so that if I click on the satisfaction display it will pop up a window telling me how many customers are unhappy and why. Also the satisfaction is dropping to the negative, and it doesn't make sense anyway, because the arcade is packed with customers. If they are so dissatisfied, why would they all be there?
4. I didn't see it explained what the non-game devices do and how they affect the customers - neon lights, chairs, tables, etc.
5. The games don't seem balanced. The arcades and especially the tables games are not cost-effective. The best bang for the buck seems to be the 3rd level pinball (costs $750 and earns $50). All the other stuff seems useless to build except to meet the challenges.
