I loved this game so much...and then it just stopped, which was depressing. I understand you where having issues making the game, but if you continued it on steam or not I would definitely play it.
Is it possible to add a cost for the buy x10, so you don't end up only buying 5 since your funds are low. Its nothing serious i love the game even without it, but i think it would make the buy x10 feature more easily used. It's difficult from my view to calculate the cost of 10 buys, since I don't know the rate of increase of the cost. Other then that I've spent the last, at least week and a half, playing this game and still am not bored. great game!
