I wouldn't call this a completed game, not very well thought out/rough mechanics plus a lack of variety. Not to mention I lost and got the victory screen...
I do like the concept and the fact that ships have a anti missile system.
I think if you took this control style, fixed it up, and made a large variety of ships (maybe even multiple factions) and such you could make a game with epic fleet battles rather than what seems to be yet another crappy mobile game
Now you just have to make a endless war defence 2 where you have to defend an entire town from more than one direction instead of just 1 lane of enemies attacking your defencive line.
