I'm on Level 3, and I haven't found answers to these questions, and I have a few suggestions embedded as well.
-What do the status bars in top right corner on Wealth and Armies indicate? They seem to grow, but I don't know what they are relative to.
-Is there a way to see upgrade benefits? I saw an equation that they are all following a formula via the wiki, but seeing in-game would be nice.
-As a related questions, at least as far as army camps go, is it always better to upgrade the cheaper of the two? With mines, I think it may depend on the ores it gives and the smelters you are running before blinding choosing the cheaper one.
-Is there a maximum amount of ore you can hold? Seems like there should be. I know you can only accumulate 2 hours worth, but it would make sense if there was a maximum capacity of ore that you could hold as well. (Maybe same for bars, etc?) Meaning, if you don't run a type of smelter, you can only accumulate so much of that material, even over several 2-hour periods. This could be based on number of territories you hold.
-Pop-Up windows seem to go away very fast. e.g., I just got the market, and I was 1/2 way through reading the text in the Yellow box before it disappeared.
-Some territories appear to give wealth (small amount compared to bonus) but others don't give wealth (maybe territories with buildings?) Is there any rhyme and reason for this? Other than clicking on the territories, is it visible anywhere?
-I suggest making claiming territories be a two-tap action. First tap brings up info on the block, second tap gives you option to claim it with armies. I saw the FAQ to get details about bordering territories, but that is many taps just to see info on one territory, that you have to repeat the several taps to see a 2nd adjacent territory. Doubling the total number of taps to conquer all territories is a small price to pay, i believe, compared to the alternative of a 3-4 tap experience just to check out a territory's info. Further, this info window could show information on taking the territory. For example, with the Joint Strike AP upgrade, the info window could tell you how many armies it would leave you left with after attacking. This would also prevent inadvertent claiming of territories.
-The menu bar is a bit cluttered, would two rows be better? Including the down arrow, i've got 9 boxes to choose from. Very small when playing with phone horizontal.
-Can there be an indication on the smelter tab if a smelter is awaiting resources? Maybe highlighted in yellow?
-What is an alloy? Basic Marketing Tech increases ores by 15%, but Intern Salesman Tech increases alloys by 15%. What's the difference? The Ore Tab includes (on level 3) Copper, Tin, Iron, Zinc, Nickel. I couldn't find a separate alloy bar.
-After capturing a full bonus, it glows with a fire background until I tap again. Should this time out?
-API bonus (coin upgrade) I was asked if I would like a %age more API for paying 30 coins. I said yes. I should have assumed this was a 1-time adjustment, but I made an error. Maybe change the language to be: Would you like to earn X more API on this level for Y Gold?
-A general strategy question: Is it better to use gold on mercenary troops before upgrading army camps? Or is this not a simple answer.
-WRT Coin Purchases, what is the (0/5) box for. E.g., Time Warp - Advance Time for 1 hour costs 100 gems, the block says: Purchase (0/5) 100 gems. Can you only buy this upgrade 5 times total with 500 gems? Does it change when its 1/5? Similarly, with Multi-Level, is that a 1-time thing that you can play 2 levels at once, and you can only do it 5 times? Or if I make 5 purchases, can I play 5 levels at once all the time?
-What are the calculations on AP if you quit in the middle of a level? Right now, I am 79% through Level 3 and am offered 16.5 API if I were to quit, but 31.25 if I were to finish. If I go back to this level subsequently, will it be reduced as if I won it instead of quitting part way through?
-I may have missed it in tutorial, but does it ever say that Techs are level-specific?
-Is there a timer for drafting armies?
