It is a kick-ass game (warning, long text)
NOW for those who still do not know weather to play this game or not: do it. This game has everything, You could dream of for a flash game:
-simle and addictive graphics (green, black and red - what else can You wish for?)
-hi-lvl customisation (lots of parts (bullet shooters, rocket launchers, beam shooters, cannons, core heals, shell heals, energy restorers, thrusts (my favorite), and even more. And the best part, THEY COME IN DIFFERENT SIZES, SHAPES AND ATTRIBUTES (weight, core and ammo bonusses,...) By the way, the weight of each part affects Your acceleration)
-a unique mix of tactics, shooter and rpg game makes this game most enjoyable game of its genres (Imagine you can build any size, shape, strenght and speed ship, what You would do? how many enemies can You take single-handed? Or maybe You want a very fast ship so You could dodge bullets? Or do You prefer to have a high lvl of Your helth restored automatically and all the time?)
To conclude - as many people already said, I would pay some money to buy this game :) but it lacks a better story - just going on a missions isn't enough - You have to have a storylime twist, like a battle commander treachery, or maybe the commander wanted enormous power so he went to the center of the earth and awoke the power he could not controll. later the power overwhelmed him and things got even worse, like in a pit of hell. something like that :) everything else is just great.
Of course I hope to find a larger selection of parts and stuff on part 2.
