Nice but.......
Well its real good but there are a few things that could be improved like:
Gamplay-Make it so you can use numbers or keys to make units.
Graphics-They are decent but some enamies are just like a piece of paper.
Units-Good specials but the cool down is a killer.Make it so like if u want to make a special u have to click the unit.Another thing there is no limit to units.I could just mass phaser platforms and get to lvl 25.Plus there are no upgrades to the ships.
Overall-Pretty good game.Thanks for this cool game.=)
