Two most important things to change in this game are: 1. Adding "are you sure you want to spend donuts?" pop-up window, and 2. radio button "do not show this again" on that window that pops-up, after you choose to use energy or training vouchers right away.
Would be fantastic if you could buy a donut for let's say 100k game coins. It happens to me all the time that I am stuck without missiles for a long time, and it's a complete lock-out, so this could help.
The game mechanics, difficulty and progress balance, graphics, story, updates, are one of the greatest out there. The only problem for me was that it gets boring after a while, but I would certainly love to see more games from this developer.
I think that ranking should be changed from ranking based on current money in the pocket+stock to some sum of money+investments+assets. This way, I'm having an impression it's not telling me much.
Furthermore, it would be nice if all stock fields could be fit into one window, without the need for scrolling. Screen could be arranged in two halves. And we should see stocks that we invested in colored a bit. The only thing now that differs stocks we bougth and those we have no connection with is popping out of this grayish sell button. And yeah, the descreet text showing how much we bought and by what price. You could simply highlight that.
I think that stock refresh rate should be at least twice as quicker, and that changes of it's rates should be greater, so you can win some relevant amount of money by playing with it.
This is possibly the best online game for me. I got all the badges a long time ago, but whenever I see it somewhere, I have to play it again. High tea gets into your blood.
You are right. That is how it is gonna work in final version
