well...
it would have been better if the cannons would fire at the enemies on their own rather than you firing them...or if it's you firing, at least just make use of one powerful cannon and summon other engines to aid you. something like epic war type...
Uhm
As a game this has great potential but it shouldnt be a shooting game as much as it should be a strategy game. Maybe shooting one turret while the others fire independenlty would be nice but eh.
cool game
just that the levels are too dificult
Okay
It'd be nice if you could watch the guns fire at the helicopters instead of firing at em' yourself, makes it easier, it'd be more like a stradegy game that way...
Too hard...
Either having idle turrets auto-fire or being able to select all turrets at once would add a lot to this game. Great job none the less.
