A fun little game for what it is. There are some flaws though, and in my opinion the good outweighs the bad here. Wanting to just play though the game, I built ships how I would like to. But the games restrictions are just too much. Add too much and you get a bad grade, which in turn will hault your game upon any boss because you need better ranks on stages. To get better ranks requires boring and tetidious rearranging and picture perfect accuracy. Upon reaching the last boss, the game wanted me to go back and get 15 more stars before I could beat the game, and that really ruined it for me.
Most of the time the game just left me stressed and frustrated. There was only one time where I really felt enjoyment in the game and it's upsetting to say so, because this game looks promising, but it fails to deliever the joy and fun I've had with other indy games of this style.
If I could play the game how I want to, this game would be worth it. But with the restrictions and constant remindering to go back and get better ranks at stages you've done before, I'd have to recommend a pass on this one.
