Great stuff
Really great game, brought me back to play again.
Only thing I didn't like was the axe - The only thing going for it is it's long range guns and their wide firing angle - both of its special abilities mean that it doesn't shoot them and all of your allies have been killed by the zeppelin on the second round while you are still half a screen away. It's slow and doesn't have enough armour. Because it is so slow the dusters can run rings around it and jam the guns for three turns. It then runs so slowly there is no chance of escaping so it just a matter of how many shields you have left until the whole group of planes takes you down. Given how much grinding you need to do so as to buy it it was a real disapointment, and made me decide not to bother grinding for the zeppelin, I can't be bothered to do another 50 games with the bart to make enough money. Grinding is all well and good, but there is such thing as too much! It really needs loads of armour so that it will be able to hold up among the dozens of little planes flying around it, or better skills that enable you to make use of the guns (preferably both)
But until the axe it was a good game.
