I manage to see 5 seconds of intro, but the historical accuracy of those 5 seconds is enough to make me suspect that even if the game loaded it would make me want to commit physical violence against the author.
It asks me whether I've trained before, I say no, and it doesn't give me any training. So what was the point of asking? I can't be bothered to trial-and-error my way through. 1/5.
Setting keys is still broken. And since there's no indication of progress and tanks keep respawning when I kill them I'm assuming that it's not possible to get beyond level one.
Gameplay is nice and simple. UI could be improved a bit. It took me a long time to see the "Levels" button because it's nowhere near the replay/next buttons. And having to reset upgrade points and then fill everything out from scratch is a pain in the arse - better to have decrement buttons per row plus "Reset circles", "Reset squares", "Reset triangles".
I'd like to echo the comments about having to click loads of times. I would try to complete the game if the number of unnecessary clicks weren't driving me up the wall.
