Ok, so I played it for a while and thought I would make a review.
Things to improve:
1. A menu beside the buy menu, that show the most amount of money that you have spent on that particular item. That way you will know how much you must sell it for to gain profit without you having to write it down separately.
2. Money left after purchase should be shown, just so you know how much money will be left.
3. A separation of numbers, like instead of $14563325455 it could be like this for easier reading $14,563,325,455.
4. The quantity of one´s items should be shown separately so that you can keep the same amount that you want to buy without it changing in the "buy-quantity" manu. Like this:
Quantity: 400 Buy-quantity: 20 BUY SELL
5. It would be nice ti be able to loan money even if you have no property to live in. Because when you´re fresh in the game, that´s when you need money, not later when you have like a billion-zillion-gadrillion dollars.
6. A spell check in some places would be nice. Sale should be Sell. Especially the help manu needs some cleaning up.
7. The flying is to expensive as of now. It should be like 200:- or 100:- otherwise you spend to much money on flying around trying to find the good prices. It could even be like if there is a place with especially good prices, then make it more expensive to go to better places. Like somewhat good prices = 100:- and better places = 500:- etc.
8. Cheaper houses if you want to keep the system where you have to have a house to be able to get a loan. Otherwise when you finally get a house you wont need a loan anymore as mentioned above.
9. A bug I found is that when your car gets stolen in the menu it stills says that you have a car.
10. A fun feature would be if you could pay someone in the game later to get more frequent price changes and stuff. That would make the game more fast paced later and also it would make it an option to spend money on something later in the game, so it would be wise to make it a bit pricey to only make it available later.
11. If you buy a plane it should lower the cost of flying and when you have the most expensive one, it should be free.
12. A pop-up when you hover over cities to go to, that shows the prices for all the stuff there. It should only come up if you have visited the city already. If there is commodity changes, the you would have to visit that city again to see the pop-up. That way you can keep track where you have bin and also keep track over prices that you have use for.
Hope you liked my review and keep making games because it is a fun game, it only has some flaws for you to iron out. Keep it up =D The second game you make, will perhaps be a smaller masterpiece.
Well, have a nice one!
