Good game, the tank modifications section is great if a little overwhelming first time. Biggest critiscism is there's no save game. For a game of this size, that should be a must - I played over 45minutes one day then had to restart the next. For that reason I've marked it down.
I was quite enjoying this game. Until lvl 10. I don't believe it is possible - if it is, the timing must be so exact as to only be possible by fluke . Shame :(
