I was amusingly having a sleepless night last night and was using my Iphone when I got the alert that the game had been released, so spent a couple of hours playing.
Firstly, I really like the concept, while the timing took a while to get used to, especially when I was learning the screen (for example I didn't realise at first that there were two buttons for each unit type, attack and defence), I eventually got the idea and then found the game very addictive.
It took me a bit of getting used to the layout but I was able to beat the easy AI without too much difficulty, ten straight wins, though admittedly I probably had good luck in what units I had.
To those having trouble, a couple of things to bare in mind, firstly, time only ticks when your on the build screen, you can take as much time looking over battle results as you want, also note that a lot of things you flick past have information beside them, for example the name and cost of each unit or building.
I do agree with Slj that the campaign screen (the one you get where you select powers), was problematic, since while you can hit the info buttons for the descriptions of your units its not clear what button goes where or how to get a breakdown of your powers.
It'd also be nice from an access perspective to have the messages that appear at the bottom of the screen read automatically, or to be able pause the timer while you read them, I actually missed the tutorial since I didn't realize that the messages were way down at the bottom.
I will say the difficulty is steep. I slaughtered the easy Ai even before I knew what I was doing, but I have only been able to win one match against normal thus far.
Part of this is getting used to the strengths and weaknesses of what units you have and how different resources interact,though I do wish there was an ai gradiant between easy and normal, since it seems the jump there is pretty huge. This is also where not being able to efficiently examine your units descriptions is a miner pest, indeed while I gather that the point is to try and take advantage of the enemy's weaknesses, I haven't yet got which unit is which type or which type of unit is stron/weak against which type, though of course part of this will come with familiarity with the game.
I also am a little sorry there isn't more flavour text in the game, for example the names of the attacking enemy civilizations, since while I get that enemies are created at random, having a name or two would make the game feel a bit more like a battle and a bit less like a weighted set of dice rolls even if that is what it is.
Similarly, some more atmospheric combat logs might be nice.
All in all though, definitely a nice idea for a game, and I'll look forward to getting more familiar with all the different unit types and how best to use them.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
