Lovely little game, but I'll agree with earlier comments, that After a point, it's very easy. I think it needs some way of making it harder to go deeper. After Cooling V, there wasn't much challenge.
But other than it's speedy exhaustion, I can't fault it at all.
Oh, also, I like your use of those archaic names, wolfram and smaragd.
That's all.
Had to say I didnt expect much of the game, but it is brilliant, got to think of strategies in two fields at once and all. not much point in the allies turning up though. maybe one with brits and japs in as well to follow?
is it me, or are the rocket turrets way too tough. the enemy just manage to put down blocks of five of them, and none of my stuff can get close to the first two, let alone the rest
