To be honest, I wouldn't have bought this game were it not for the huge discount I got for it. So I went into it not much expecting, but I am getting some pleasant surprises. Don't expect anything fancy from graphics or sound - they do the job, but that's it. As for so many Indie games, this one is all about the gameplay.
Basically, this is a tower defense game: you have to gather resources (happens automatically), build ever more powerful units, and research upgrades for them. With these spaceships, the goal is to reach the mothership of your opponent, at the other side of the playfield, while at the same time defending your own mothership against incoming attacks.
Since there is only one path between the two bases, most of the time the two opposing fleets meet somewhere in between, slowly (or faster if you're good) progressing towards the enemy's side. There is not much more to it: the core gameplay is dead simple, but it has something about it that keeps the attention going. One does have to make important and micro-strategic decisions: does one invest the resources gathered into new ships, or rather into upgrades? And there is a neat supra research-tree, which allows you to spend resource points that affects all or any of the three factions in the game.
Part of the attraction of the game surely lies in the excellent way it is embedded in the Steam cloud, with achievements, trading cards, multiplayer options, rankings, etc. Name it, and this game has it. So for the moment I want to try going up on the ladder, or win my first multiplayer. It's a simple game, but it does what it wants to do pretty good.
