Great game, not to difficult to finish, moderately challenging to finish with 3 stars each, rewarding to get top times, where you have to squeeze in extra flips and keep speed up :). Would love to play more levels :)
At first it seems to be a great game, but the randomness kills it beyond fun. to draw 3 utter shit cards in a defend phase, then see -46 -32 -20 something is just unbalanced.
build a bus stop in day 3, then in day 4 bus wil stop every now and then, and you can just get money just on day 1XD.
first 3 levels were ok gets a bit boring
Flagship / no flagship means if you encountered a flagship on that stage (ie big ship / zepp from the enemy).
My tactic which worked 1 or 2 goes every stage:
start with cannon only, upgrade supply line 2/3 then upgrade recycling. make a frigate and helicopter when enemy sends a bomber/submarine.
Dont forget to upgrade using skills (you get from 1-3 stars in a stage.
Assuming latest stages:
Destroyers as main force, back up with frigate for anti-nuke sub. Bomber only when you can put out a lot of air force to shield it, and when enemy is in a small area.
Battleship for taking out fortress / base defense.
for flagship: make sure you have full artillery battery, send in cruisers /battle ships to. your artillery battery should take m out for the most part.
Good game tbh, people need to learn not all games are easy and short. it has a tendancy to drive you back when a big ship comes on the scene (hindeburg was amazing :P).
But all units have a decent role, and can be usefull.
Destroyer spam sucks, if 2 bombers come and you dont take m out fast enough :P. i rather use all units (or most)
