Got this app looking for something to satisfy my Sid Meier's craving, and while not as epic as RR Tycoon, this is a good quality strategy game. It still has some bugs in it, but that's pretty standard for a new app. Very addictive otherwise!
Things I'd like to see in future versions... A way to save progress on a level in order to try different strategies without completely ditching your progress. A scoring system to track high scores and challenges on levels, and ability to challenge friends. Ability to save and/or share solutions for future reference or bragging rights. Store purchased trains rather than trashing them when modifying tracks. Ability to pick which car gets removed rather than ditching all the cars behind the one you want to remove.
Some other thoughts as well, but this is a good starting point!
Oh, and I tried to purchase some hats, but the marketplace is currently buggy.
Thanks again for making this quality strategy game. Can't wait to see where you take it from here!
